What medication is the best?

Ive been on Vyvanse for about 2 years now, and I was wondering on some advice. Im on it as we speak so sorry if i have a ton of spelling mistakes

I assume because I am fat also, I was prescribed it for its binge eating disorder qualities (even when i dont have said disorder.) I have been feeling like complete shit, despite lowering or increasing doses on Vyvanse.

I fit all of the regular symptoms for it, with the added bruxism which causes me to grind my teeth and also have bad anxiety attacks. which is apparently also apart of Vyvanse but

I was wondering which medication would be best to switch to?

Or even better yet, how can I deal with my symptoms to make them less of a problem?

for context, these are the side effects I have.

- sleepiness

- dizziness

- headaches

- dry mouth

- diarrhea/constipation

- nausea

- decreased loss in appetite

is there anything i can do to manage this? its been making my life significantly harder. also for record, i do take sertraline at night for my insomnia, I didn’t figure that it would affect me but it could
