Found this thread a bit late, but thought I'd chip in for anyone else reading down the line. Getting off the medication is the real challenge for most people because the hunger just snaps back. I found that keeping a strict routine for my first meal of the day helped stop the weight from creeping back.
I switched to using Shake That Weight for my breakfasts since they're a UK company and it costs way less than the injections did.
It keeps the morning calories low without any effort. Just make sure you stay on top of your water intake to avoid the headaches.
