I have a paralysed arm as a result of nerve damage. I take low dose (20mg) of Amitriptyline for pain relief at night before I go to bed. I have no depression problems, the drug is purely for pain relief. I qualified (PADI Open Water) last year & I was not on the drug at the time. What are your feelings of recreational diving on that drug? If I absolutely had to, I could come off the drug. I go to the Red Sea in 3 weeks time.
