oh yea alters can go against what you are doing. in fact thats one of the diagnostic criteria for having DID. you have to have at least two alters that repeatedly take control, that have their own way of being that isnt shared by you or any of the other alters.

what that means is they have their own purpose /jobs, ways of eating, ways of drinking (not necessarily alcohol but its been known to happen lol), ways they like to dress, what they like to do.

Im integrated now but one of my alters used to smoke when I the host never smoked, go out to the bars when I never frequented bars. one of my alters absolutely loved eating mashed potatoes, broiled steak to medium rare and string beans. me Give me a pizza any day lol and some days a bag of chips and in my days of having an eating disorder nothing for me thanks, but that alter made sure I had three nutritious meals a day. I believe without that alter whos job it was to make sure I had enough nutritional food a day to survive I would be dead now.

having an eating disorder myself I know how it is to not want to nor need to nor crave food but having DID I got luckier than others I knew with eating disorders that were not DID and ended up dying of starvation and other eating disorder problems.
