For the last 2 months I have been suffering with waves of nausea and dizzyness, usually worse first thing in the morning and around 3pm. I've also lost a fair amount of weight recently but these last few weeks seem to have put it back on but around my stomach area. My last period only lasted one day but was normal (not any lighter that usual). I also find I'm sleeping a lot more than I usually do in the day, after work but find I'm very restless at night which is unusual for me as I sleep quite heavy. Also I have been sick every time I drink alcohol lately which again is not like me. I'm 27 year old female. Any help/advise will be greatly appreciated.
