No loss of appetite. I mean when I was nauseated I wasn't wanting food of course, but when it would pass I would be SO fucking hungry. But then if I ate something I'd get the nausea again, so I wasn't eating even though I wanted to. I lost a good 15-20lbs. during the past two weeks and it will probably continue as I'm eating smaller, lighter and probably healthier meals right now. Like right now I have a subway sub (ham, lettuce, tomato) and some baked chips compared to my usually burger and fries. I also haven't had any soda in 2 weeks either.
