The last 2 weeks about my weight has been going up and down not by a few pound but normally 5lbs to 10lbs at most. And I have never had this go on and I asked a friend and they said it may be because of some stuff I got going on and I mean stressfull stuff. But I don't know whats with it, im 185lbs normally and have dropped to 175 at the lowest. Whats going on?!?!?
