Hi, I have had a sucessful kidney transplant since 2001, and am taking sirolimus 4mg OD, azathioprine 25mg OD and enalapril 20mg OD. I also take 30mg of citalopram daily, due to stress related to an ongoing divorce, but still suffer from very bad headaches, neck pain and anxiety. I saw 'Kalms' in the pharmacy the other day. Are they safe for someone like me? Do they work? Thank you, Debbie
