I am also Bipolar and took Seroquel for two years. I lost the battle with weight gain most people do while taking psych meds. I was still binging after I stopped the Seroquel and started Latuda which is weight neutral. I have been binging and dieting for years so meds alone are not an excuse. Be honest with yourself and your doctor about what side effects are acceptable to you. Make a list of pros and cons about your meds. This might help with binging.

Also, push yourself to exercise if you can. Exercise releases chemicals in the brain called Endorphins that give you a feeling of happiness. You are more likely to have a tall glass of water than food after a workout.

Easier said than done - I know.
