Sometimes my ADHD meds
completely kill my appetite and I end up forcing myself to eat (like now, when I've been off them a long time & have just started back). I really hate that awful feeling of knowing I should eat so I don't pass out but really not wanting to put anything in my mouth. Though, usually when it happens, once I start eating I find I don't mind it so much.
I really don't have any advice, and my experiences haven't been as severe as yours appear to be, but I just wanted to say I know that feel
Hope your doctor can help!
