You can't get dependent on Cialis, it costs too much. My urologist had me start on Viagra/Cialis as soon as the catheter was out so I don't think it's too soon.
Unfortunately, neither one worked like before the surgery so I was switched to Levitra which did work. I have hypertension so have been on ED drugs for years.
There are also a few side effects to Cialis, it would give me these night erections that were unreal. They would last for over an hour and really hard. But I would also sometimes get leg cramps. If I skipped Cialis for a week, the cramps would go away. This was all before the surgery.
