ibromyalgia
"This medicine made me so exhausted I would sleep at least 12 hours every night and I'd feel so tired all day I couldn't get anything done. And the two nights I couldn't take it when I was on it, I stayed up for over 24 hours with insomnia. It freaked me out that it would prevent me from sleeping if I didn't take it, so I got off of it quickly. It DID help some of the pain, but it wasn't worth it."
