I've been taking Flomax a year now. RO prescribed it and told me to take in the evenings. I still have to get up 2-3 time a night with little volume each time. During the day I can generally go a few hours before I feel the need to go. Volume is more but then I drink more liquids. The up 2-3 times (almost like clockwork - every 2 - 2.5 hrs. each time) really disturbs my sleep. Should I change the timing on taking it?
