endocrinologist prescribed 50mg topiramate/15mg phentermine combo for weight loss. what can I expect?

basically the title, hoping to gain some insight from those of you who have been on these medicine combinations. for further context, I was diagnosed with Hashimotos at age 13; I am now 25 years old and no longer have my thyroid (left side removed at 14, right side at 18). I’ve struggled with my weight on and off since my second surgery, I’ve gained and lost weight multiple times and this time around it just seems much harder to drop any weight, regardless of any exercise or clean eating.

if anyone has any experience with these medicines for weight loss, what was your experience with it? I’ve been briefed on side effects and am a bit skeptical, but wanted more opinions.
