lyn, when i saw the first gp because of constipation he said to stop the tammy so i did,but it didnt stop the constipation,the next gp said to reinstart so i did,couple of wks later was feeling really weak so i went back another gp i asked if i could have 1 like every other day he said to please myself about taking it,so you see you get conflicting things from different gps,it is hard to see the same gp you have got to get in when you can,i have still got tamsolusin i might start taking 1 during the day.regards side effects weakness is there so is constipation.
