Sedation
"Have been taking 10mg for years on a semi regular basis. Only when I need a good sleep or if I slept poorly for a couple days. Don&#039;t notice the anti histamine effect, but do sleep well and rested.

If nervous system is too aroused it doesn&#039;t always work. But for me, its good. Not much side effect apart from slight drowsiness but very short term on waking."
