Drowsiness, dizziness, headaches, lightheadedness and difficulty with coordination.
Personally I am really against sleep meds because even the non-addictive ones are still addictive and clinical trials have linked them in long-term studies to depression and anxiety because it messes with your nuerotransmitters, so if you are prone to depression or anxiety, sleeping meds have shown to induce them.
The biggest thing that studies I've seen have found to fix sleeplessness is to only use your bed for sleep and sex. We are creatures of conditioning and if you only sleep in your bed, your brain will know when you are in bed to go to sleep. Plus not eating and watching tv in bed reduces annoying crumbs :)
