ibromyalgia
"I was recently dx w/ Fibromyalgia. I take 50mg of Tramadol when I'm having a "bad pain day" which is about 3x per week. Tramadol seems to take the edge off the pain as well as increase my energy level and put me in a better mood. 

Downsides: it usually causes a mild upset stomach (for the first 30-60mins), it takes about an hour to kick in, and rarely it makes me a little nauseous. 

Overall, I'm pleased with this drug. My provider had told me that Hydrocodone/Oxycodone medications will worsen my Fibromyalgia syndrome in the long run, but that taking Tramadol as needed is a good method of treatment."
