Meclizine
"Just started Mecliizine 25mg 3 days ago to treat vertigo condition. Works great, but it makes me so sleepy. I take it before bed now, and only once per day, as opposed to the recommended 6 to 8 hours. I've been dealing with nausea and dizziness almost daily for the past few years, this medication has provided instant relief, and I am now almost guaranteed to sleep through the night."
