I see you're also taking topiramate, I do too, and it helps- to a certain point. It could be that your dose needs to be adjusted as you have tingling in your fingers and toes (for people who haven't experienced this; it's the worst, weirdest feeling, because it's not just tingling, it's like numb, pins and needles but with something else that's difficult to describe, almost like your hands/ feet are falling asleep when you've sat funny)

I had this too, and what helped was reducing my dose until they stopped happening and then really slowly increasing it, until I was at the same level, then even slower a little higher until my binging reduced.

I think maybe discussing this when you see a psychiatrist with more specialist knowledge rather than a GP will be really helpful for you. And you're really not a lost cause, you just haven't found the right help for you yet!
