"horrible! if i could rate a 0 i would. started having headaches ( i never ever have headaches), got my period for 10 days 6 weeks in, bp went from 100/60 to 158/98.  missed 2 doses so i followed the directions and upon taking them and my normal dose shit hit the fan. i couldn&#039;t breathe, my heart was racing, and my bp went through the roof. i was sent to er ( after my first 2 visits) to get checked for a pe, have had a million tests done, several ekg&#039;s and have an spot with a cardiologist.  i have been waiting for the drugs to get out of my system (the half life is about a month) and i am light headed have the worst anxiety ( never ever had it before so it really hard to deal with which is making it worse), really jittery and and not happy."
