I'm no expert...in fact I'm only posting here because I posted earlier with a similar scenario. I'm 20, male, 6'1" and 195 lbs. From the age of 15 or 16 I've had the morning sickness you're describing here. I've been to two doctors about it and here's the advice I was given:
Doctor 1: "drink lots of water, cut soda out of your diet, get on a more rigid sleep schedule and try to make a habit of eating breakfast."
Doctor 2: "lose 30 lbs and cut out soda...no smoking or drinking."
Although I don't feel significantly better, as I still get morning sickness, I can honestly say that when I drink tons of water I feel a smidge better. I can't bring myself to eat breakfast though.
Good luck...I'm searching for answers and have scheduled an appointment with a specialist next month. If I'm told anything new I'll let you know.
I am a 41 yr old woman who has experienced nausea since I was in my mid teens. After a couple of hours I feel better.
I've yet to find the cause of this.
