"switched from generic Flomax to Alfuzosin for BPH after dizzy episodes on Flomax were severe enough that I would have to lie down.

However, while there are no sudden dizzy episodes with Alfuzosin, I am experiencing an all-the-time feeling of being tired and weak. I still can get through my workout, but the general overall fatigue is bothersome."
