So a few weeks ago my dr recommended taking a half tablet of unisom (over the counter) before bed to treat my nausea. I didn't worry about it until yesterday when I was puking TONS. Took it 20 minutes before bed, woke up today and nothing. No nausea at all. I've been waiting for it to come back and it hasn't. It's only been 1 day but I wanted to share it because I was actually able to get out of bed today!
