Not really. I wouldn't trust your average doctor if I was inquiring about the use of cialis and food nitrates. Before I wrote my question I actually found an online doctor response saying that he thinks it's fine to drink beet juice and cialis. It really depends on the amount of beet juice someone has per day right, but he did not qualify his answer, nor probably researched it prior.
Doctors will know a so called catch phrase, don't mix boner pills with TNT type drugs. In regards to food nitrates some will say it's fine, and some will say avoid.
The study I posted in the other nitrate thread had patients loading on 7 days cialis, 20mg per day. Then they introduced a normal dose of nitroglycerin to see what happened to the BP. The abstract results seem pretty tame.
Anyway I have more trust in a reputable rep like yourself cooper, than the average Dr I may encounter in day to day life.
