For that past couple of weeks, I had been having trouble falling and staying asleep. My friend suggested I try Unisom SleepTabs, so she went to bought some at the store. That night, I took the recommended dosage. I had no trouble falling asleep within 30 minutes to an hour after taking the tablet. I slept the whole night through until it was time to wake up the next morning. The only problem I had with Unisom SleepTabs was the side effects. Upon awakening, I realized there was a problem. I couldn't fully wake up! The rest of the day, I felt sluggish and lazy. All I wanted to do was go back to bed and sleep. Besides that side effect, I felt no other side effects. They worked as said, and actually gave me energy the next day! The only warning I give you is that if you take them one night, plan on doing nothing but sleeping the next morning/day.
