Thanks everyone here for your comments. I experienced severe insomnia, restlessness, and anxiety while taking Flomax. Also, stuffy nose, swollen throat, and shortness of breath. Since insomnia, restlessness, and anxiety are not widely reported side-effects of Flomax, at first I didn't think that was the cause. Instead I thought I was having a relapse of the major depression that I recovered from 10 years ago, which began with similar symptoms. That scared me! Then I talked to my doctor, and he told me to STOP taking Flomax. I did, and within 24 hours, the insomnia and restlessness are gone. I don't know what our next treatment option is going to be, but it sure won't be Flomax. Flomax had me flummoxed!
