Greetings, 13. Let me agree with Smokie - do what your doctor says. I had surgery on Feb 4, catheter out on Feb 13 and Feb 16 managed an erection of about 80% and my wife and I were overjoyed - didn't do anthing with it but it was a great encouragement. My doc had given me some samples of Cialis and said take them a couple of times a week. When I got the erection so quickly I called the doc's office, talked to the nurse, and she said if you don't need them don't take them. That was a BIG MISTAKE. I never got more than 80% and even started to regress somewhat.
When I went for my second 90 day PSA test, was given more samples - this time Levitra. Took one and was back to 100% of presurgery. There is a reason the doc wants you to take the pills after surgery whether they work or not so my suggestion is to do it.
Now, I take the ADC equivalent of Levitra 2 times a week right before I go to bed. If I take it in the day I do get the face flushing and stuffy nose, but when I take it at bedtime I never know I have any side effects. I seem to be ready to go anytime with this maintenance type of approach to taking the pill. By the way, look back at several threads regarding ADC - I have found them perfectly acceptable regarding their product and very customer friendly in dealing with them. Don't pay the high prices in the USA.
Best wishes - trust you will move right on down the path to complete recovery. David
