flomax and insomnia

I was having trouble sleeping. I thought it was due to fear of wetting the bed, stress, whatever. But, I was trying Flomax and it wasn't working all that well for me, little bit maybe. I also had some GI symptoms. For that reason, I stopped taking it and even though I kinda need some protection, now, I just feel and sleep a lot better. I wonder if others have the same problem.
