insomnia
"I had a very negative experience with this drug. I suffer from initial and maintenance insomnia and nothing has worked but this drug did something others didn't - it made the insomnia worst and I couldn't sleep at all. I was in and out of sleep the first couple of hours, I took it at 9pm, and then couldn't go back to sleep after waking up at 1:30am.  It got me wired. Also, the little time I did sleep I had VERY weird dreams and it made my feet (mostly toes) hurt a lot.  Very bizarre experience and a huge set back for me :( 
I took 15mg dose, sample from doctor."
