Hydroxychloroquine
"I have been taking hydroxychloroquine for 6  Years.   I have primary sjogren's, hashimoto's. Before, I was tired all the time and could not lift a 3 lb dumbbell. Sometimes I could barely walk, my neck, knees, elbows, etc. we're always in pain. The bottoms of my feet hurt - I dreaded getting out of bed in the morning. Initially I took 2 of the 200 mg tabs/day.  Years later this was cut to 100mg/day.  3 weeks ago -- at my request - doc let me cut it in half to 50 mg/day. I am 58 years old go to the gym 4-5 X/week. Yesterday I did chest press w/ 60 lbs, heaved 50 lb barbell over head, did rows with 90 lbs... I love plaquenil."
