Help, I really cant understand whats happening! I am kind of constipated... I have put on 4.5 kgs in the last 6 days. I took dexaprine for like 10 days to study for exams and i guess a better.. I have been constipated since then.. I have been putting on weight non stop. 5 kgs in 6 days is ridiculous. I have never bloated up so much since the last 6 years. I use to be fat before but now im fine skinny. im 5.11 - 85.. i should be around 78. Help!!! What can I do.. I have doing lot of weights and half hour of cardio everyday.
