Does anyone know a good (any) resource on the effect of specific medications on the vitamins and other nutrients in the body? (i.e. is there an Adelle Davis of the Internet.) The reason I'm asking is that for the last two weeks I've had this excruciating lower back pain (pinched nerve?), as well as the occasional leg muscle cramp. (commonly signs of lack of calcium) This coincides with a new regime of Permax (still ramping up) and 3x2 Domperidone (anti nausea). And no amount of calcium e.a. helped much. I'm currently trying Folic Acid, which seems to help. I have already stopped the Domperidone which did seem to help somewhat. But if I cant get out of bed because of the side effects, I dont need to worry about tremours or dyskenesia etc. -- Frans van Duinen (416) 652-8580 Toronto, Ontario
