"i have been on amitriptyline 50 mg at night for 3 weeks and my pain has subsided a little.  i have rheumatoid arthritis, psoriatic arthritis, osteoarthritis and fibromyalgia so i have been living in chronic pain for many years.  i am also on prednisone 9 mgs daily, which my rheumatologist is tapering me off of slowly. i also am on hydrocodone 10 mgs, 2 tablets 4 times daily. my doctor just increased the amitriptyline to 100 mgs at night.  i will share my experience with this dose in another 3 weeks or so."
