Meclizine
"I've been a dizzy person all my life and I just always managed it. Then in the last few weeks, it has been worse than I've ever experienced before: dizzy spells, sensation of spinning. Nothing extreme but enough to keep me in the house a few days.

Took a 25 mg pill. No quick relief, but within an hour, there was a noticeable difference. Basically the screws tightened up and I wasn't as dizzy. Then, after 90 minutes, the vertigo was mostly gone. After 2 hours, it was totally gone.

I'm still a bit flabbergasted. Did I just suffer all those years for nothing?

Cheap drug too. Easily accessible, even over the counter.

Only complaint: A little slow to work."
