Ok so I took 50 mg a day for two weeks then increased to 100 mg 5 days ago. After the second dose I started getting sick. I take it with my dinner around 5pm, as I was told this would help with stomach upset. But by 10 pm I get an awful headache, I get hot, and somewhere around 11pm, I start vomiting- violently! Then chills and fever that doesnt let up until around 9am. Is this normal? Because Im not sure its worth it.
