For the last several months, I've noticed small white crystals with each bowel movement. I just recently decided to take apart the capsules of Effexor and the crystals in the bowel movements look exactly like crystals from those capsules. Am I right to assume I'm passing all the Effexor through my colon and not absorbing any. I hate to discuss this with my psychiatrist in person. Should I continue taking it or is it a waste of money?
