I'm in the sad minority where I had binge eating disorder well before my bipolar diagnosis. I cannot blame my bingeing on meds or my illness. I wasn't diagnosed till relatively late in life (32?) but I have had problems with food since age 4-5. Maybe always self-medicating but really hard habit to unlearn.

Definitely if you eat a lot at night, you won't be hungry the day after... not sure how meds are involved though.
