I started talking Orlistat yest. only once before my main meal... later that night I had very strong diarrhea and stomach pain... I had insomnia, started coughing..and had trouble breathing also I know it sounds irrelevant but my teeth did ache... the next day at 8am (was up all night running 2 the bathroom)... I threw up twice. and here I am sitting in bed exhausted and still have diarrhea. Are these side effects of the drug or is it food poisoning since my main meal was junk food last night? Thank u.
