Flomax
"Initially, I took the low dosage and flow improved for about a week.  Then the condition worsened.  My doctor then upped my dosage to two pill per day.  Same thing happened initially - flow improved and then reverted back to the prior condition.  But as I continued to use the drug (2 times a day) the improved condition returned.  Sometimes the flow is better than other times - like when my bladder is more full.  Trips to the bathroom at night were reduced to 0 to 1 time.  

Side effects.  Initially, I experienced many side effects - runny noise, minor headache, aches and weakness in my back and shoulder, and retrograde ejaculation.  Retrograde ejaculation is the only side effect that seems to persist."
