Lamictal with adderall and vyvanse for mood and binge eating?

I just got an rx for lamictal. Half of a 25 mg for 2 weeks then 25 for 2 week then 50 etc.

Currently on 10 mg vyvanse in the am with 15 mg ir adderall 3x a day.. the vyvanse does nothing. The adderall is good. I’m currently not taking the adderall till I can get the brand name to try.

We’re hoping to stabilize my mood with the lamictal. And the vyvanse is supposed to target my binge eating. Doc said the lamictal should help with that?

Anyone have experiences with this med combo for binge eating and mood without it effecting your ADHD symptoms?
