Week 3 on Mounjaro: The Great Jab Fumble
I’ve made it to the end of week three on Mounjaro! Huzzah!
Did I forget to do my jab this morning because I hadn’t packed for a weekend trip and was instead running around the house like a caffeinated meerkat, frantically throwing clothes into an overnight bag? Also yes.
In my defence, I remembered everything else. Toothbrush? Packed. Phone charger? Packed. Snacks for the car journey? Obviously. But the little pen that’s currently helping me reshape my life? That slipped my frazzled mind. Typical.
Forgetting My Jab (and Why It’s Not the End of the World)
Now, before anyone panics, it’s not the end of the world if you forget your Mounjaro jab. You should aim to inject at the same time every week, but if life happens (and it often does), you can just do it when you remember. The only catch is that from that moment on, your schedule shifts. So instead of my nice, tidy Friday morning routine, I’m now a Saturday jabber.
It’s all about the way the medicine works. With Mounjaro, you can’t just take it late and then go straight back to your old schedule. If I jabbed on Saturday this week and then tried to do it again the following Friday, I’d be sneaking in two doses within six days. The science-y explanation involves something called a “half-life”, which has to do with how long the medicine stays in your system. Once someone said “half-life” to me, my brain immediately went to the 1998 video game instead of pharmacokinetics. Gordon Freeman, crowbar, aliens — you know the one.
Yes, I am a nerd. I’ve made peace with that. Anyway, back to reality…
The Numbers on the Scale
Let’s talk weight loss!
I’m happy to report that this week brought another two pounds gone, hopefully forever. I’ll be honest though, when I first stepped off the scales, I felt a twinge of disappointment. My first two weeks had spoiled me — a glorious 8.5 pounds down in total. When you see those kinds of numbers, your brain starts to expect fireworks every time you step on the scales. So when only two pounds showed up this time, I had a brief sulk.
Then I gave myself a proper talking to.
“A two-pound loss in one week is fantastic,” I told myself sternly. “Sure, those four-pound weeks were amazing, but that pace isn’t realistic long term. A loss is still a loss, and progress is still progress.” Sometimes you really do have to have stern but loving words with your own inner idiot.
Once I’d got over myself, I realised that ten and a half pounds in just three weeks is something to be proud of. That’s nearly a bag and a half of sugar. If I keep this up, I could be celebrating a full stone lost by the end of my first month — before I even need to crack open a new Mounjaro pen. That thought alone is enough to make me stick to my plan (and maybe even drink some extra water like a sensible adult).
To Increase or Not to Increase
Speaking of plans, I’ve got my first check-up booked for the end of next week. That’s when I’ll have the option to increase my dosage if I want to. My pharmacist has been very clear that there’s absolutely no pressure to do so, and honestly, I don’t think I will.
Here’s why.
My appetite isn’t quite as suppressed as it was right at the beginning, but it’s still noticeably lower. I’m still seeing results, and I’m not spending every waking moment thinking about snacks, which, frankly, is a miracle. So I figure there’s no point fixing what isn’t broken. Higher doses can come with stronger side effects, and I’ve only just gotten past the waves of nausea from my first few weeks. I’d rather not tempt fate.
Plus, let’s be real: higher doses also come with higher price tags. My pharmacist didn’t say “more cheddar” exactly, but that’s the reality. The more Mounjaro you need, the more your wallet weeps. So if the 2.5 mg dose is still working, I’ll stick with it a while longer. No sense in spending extra to feel more queasy.
Settling Into the Routine
I will say that it’s interesting how quickly this new routine has started to feel normal. Three weeks ago, the idea of giving myself an injection every week felt daunting — like something only very organised, responsible people could do. Now it’s just part of the schedule, somewhere between feeding the cat and making my morning tea. Well, normally it is. Except for today, when I forgot entirely. But hey, nobody’s perfect.
On that note, I’m actually glad that Mounjaro has that flexibility built in. Knowing I haven’t ruined everything because I missed one dose is reassuring. Life happens, and sometimes you just need a treatment plan that bends a little instead of breaking.
Small Wins and Subtle Changes
It’s been fascinating seeing how my body has responded too. My energy levels are steadier, my clothes fit a bit better, and I’m no longer feeling the mid-afternoon sugar crash that used to send me straight to the biscuit tin. I’ve even started enjoying healthier meals again, which is something I never thought I’d say. Maybe it’s because I’m eating more mindfully, or maybe my taste buds are finally over their long-term relationship with crisps. Either way, I’ll take it as a win.
There’s also something deeply satisfying about noticing small, subtle changes. Like how my jeans don’t dig into my stomach quite as aggressively, or how my face looks a little less puffy in the morning. They’re tiny victories, but they stack up.
Looking Ahead to Week Four
As for next week, I’m cautiously optimistic. I’d love to hit that one stone milestone before my appointment. I know weight loss can fluctuate — hormones, hydration, the universe’s sense of humour — but I’m feeling hopeful. Even if I fall just short, I’ll still be miles ahead of where I started three weeks ago, and that’s what counts.
So here’s to week four: new jab day, new goals, and maybe, if I’m feeling bold, a sensible amount of packing done before the morning of my trip.
I’ll check back in after my appointment next Friday with an update. Hopefully, I’ll have a shiny one-stone loss to celebrate, but either way, I’ll raise a glass (or maybe a protein shake) to progress.
Wish me luck — and please, keep your fingers crossed that I remember my pen this time.
