morning sickness..

Ok I know morning sickness is totally normal and I can get medicine from my doctor to help control it some but I'm just curious, is it normal that I eat and say, 45 minutes later I'll vomit and its 100% stomach bile? Like I didn't eat at all? I have achalasia, which means my throats muscles don't work properly, basically... causing vomiting, indigestion, difficulty breathing when I eat, choking... things like that. I have an incredibly difficult time breathing now no matter what I eat, it used to only be certain things and I would just avoid those.... anyway has anyone else ever experienced vomiting stomach bile even after recently eating?
