"Flomax works great and quickly too, but it sure makes me feel bad.  I find myself skipping days and those days I feel much better.  When I take it I feel tired, slow, and light-headed...like I'm in a bit of a fog.  I also notice that my vision is very much blurred when I take this drug.  It takes hours after waking for my vision to be somewhat clearer.  I'm supposed to take it twice a day, but once a day is more than sufficient.  There doesn't seem to be a lower dosage in a capsule, so I open them and dump some of it out.  It's pretty inexpensive so that's not a problem."
