At night. Just began doing this. I watch very carefully how I feel. With the weather we have now, dehydration and low BP is a very real danger. Throw in these meds and there could be trouble. Then I take creatine as well, so I have to consciously work on hydrating big time.
I'm taking Flomax also for BPH. As I said, I'm older than most guys here and the extra benefit of cialis is help with BPH also. My PA was surprised that I was taking both. I don't know why because her doctor supervisor prescribed both. When I gave blood two weeks ago, my BP was absolutely normal.
