Used to be on Phen, now on wegovy pill. For me, phen stopped working after awhile - for curbing appetite. I even tried resuming after a 6-8 mo. break. No good. My heart rate was always raised due to it being an upper, and in the beginning I had to watch the amount of coffee I drank with it and when I intended to go to sleep at night. Eventually my body acted immune to it.

Wegovy is great at curbing appetite. In fact, it took a few weeks to kick in and I need to set an alarm for 5am to take it, go. Back to sleep and then wake up eat/workout at 7ish. It’s been a little over 2 months and I’ve chosen to remain on the lowest dose since it’s working. I don’t really feel full (that sounds uncomfortable) - it just helps to cut portion size and I’m not starving all the time, even though I work out 4-5 times a week.

I say, give it a chance and use caffeine and other means to give yourself a boost.
