insomnia
"Took 50mg to help me sleep. Woke up after about 4 hours of sleep. Heartbeat fast and thumping, thinking about anything and everything. Couldn't go back to sleep for a couple of hours. The day after I felt amped, jittery and like I was in a fog. Took for two nights, don't plan on taking again. Need some sleep. This drug may work well for you, it's just not for me. I recalled trying this medication a few years ago, had the same results then."
