I m 87, have long-since been unable to attain an erection, think I recall I had prostate removed, twice removed cancerous portions of colon, ending up with a Colostomy ( which I handle well and with which I have no problems .. in short, this old guy ( me ) thinks ( though he will check with his GP and other MDs ) it s time to quit my one-a-day Tamsulosin / Flomax. I read where dizziness and related side effects can be connected.
