I have a question, why sometimes even eating watermelon for example i cant keep it down, i really dont get the heaving throw up but i do throw it up like i have to much saliva or mucus and burping, sometimes this happens when eating lunch meat, am i to full? in the morning i eat oatmeal it did keep me satisfied for a 1 1/2 hours now i dont stay satisfied and am hungry again within an hour, i have lost 40# so far and have had three fills, do you think i need another fill? any suggestions.
