Hi. For the past 4 nights I've been having night time nausea, my abdomen starts gurgling and I feel full of gases (I have both belching and gas passing). Once or twice I will get a sort of heat wave and had to take off some bedsheets to cool down. This only happens at night when I go to bed and it makes me feel very uncomfortable. About two times in the past days after I have had very big meals I have had the nausea and feel fatigued. Some background: college student; I have been under my normal/healthy weight for some time now; I'm not eating properly as I hate the campus food and probably the reason why I keep losing weight; I have grown a little unaccustomed to big meals with meat and fat in it so whenever I have one my stomach turns really sensitive and I feel heavy and full for a loooong time; sexually active but on the pill and ALWAYS use condoms and always extremely careful; last sexual activity about 3 weeks ago. Please help... :-(
