Here in UK you can get a private body composition scan locally for around one hundred to one fifty no doctor needed. Good baseline before starting and again at goal to see if muscle building makes sense for next phase.
Honestly, my weight before was making me miserable every day anyway. Meds suck sometimes but it's a different kind of feeling. Trading one symptom for another's been worth it. Nausea beats what I had. But if I was puking daily, I'd quit.
stopped once for almost two months by accident. gained it back. went back on the dose i was at and it took a couple months to kick in again. was bummed because before the stop i was dropping steady. but eventually my body shifted back into loss mode.
that rebound weight is not weird — some ppl think breaks 'reset' receptors but the data shows prior use can dull future effectiveness. good news is you're back to where you were and losing again.
I think the tricky part is that coming off too soon means your body fights back harder than you expect. It wants to return to what it knew, so the cravings ramp up and the regain happens fast. If you're planning to stop eventually, staying on the lowest dose that lets you live normally for at least half a year really does help reset things. Your metabolism needs time to learn the new normal.
