I can, but I trust my own research more since the physician's desk reference is really not very accurate in terms of what's safe and what's not. It just wasn't tested so it doesn't have the information. Dr. Hale has the best information since he's the only one testing anything. It would be easy for me to look up all the pain killers but I don't know what else people may have had to take (blood thinners, antibiotics, antinflamitories, muscle relaxants, anti-anxiety...) all of a sudden that leaves me with a list that is huge so I was hoping that I could get an idea about what to expect level-wise (post op morphine or percocet?) you know what I mean? Then it would make my work a little easier. It's not always easy to do all this typing!! :-)
