I am having carpal tunnel surgery on Tues June 7th. I have been on Phen for a month now. I have received conflicting information on when to stop. My primary care dr said I could take it up to the day before surgery. Per the surgeon I was to stop Wed but got the message after I had taken the pill. So I stopped yesterday. Is 6 days enough time for the Phen to be out of my system for the surgery?
