I started throwing up about 9/10 months ago randomly. I had my gall bladder removed hoping that would help and it did nothing. Nothing sets off the vomiting, I can eat or not eat. Doesn't matter what I do or don't eat. I have had a scope done and nothing was found. I've taken pills for acid reflux and they didn't help. The vomiting happens at anytime, sometimes numerous times a day and sometimes not for days at a time. I do not feel nauseous before throwing up, sometimes there is no warning and sometimes my throats feels dry and I feel like I am going to have diarrhea. I do not get stomach pains before or after.
