I know with some of the medications out there, there is good reason to fear. I know I was not always on board to take my medications over the years. But now I know that I need them, and I am fine at this time taking the meds.
The recent problem I encountered with current med, is if I miss a dose, I can't sleep until I take the missed dose. I bothers me, but I can't get back off of the med cause I want to sleep - if I don't get enough sleep I suffer sleep paralysis and that scares the hell out of me.
Good luck, if you can't get your current doctor to help maybe you can see another doctor.
