nausea/vomiting
"I have poor tolerance of many medicines but was given Meclizine when I became extremely ill on a cruise. It (chewable form) calmed my stomach within 1/2 an hour and gave me the best night's sleep in a long time!  Next morning, I was like a new person. I used it again after gall bladder surgery when other medicines (Zofran, Compazine) produced horrible side effects, & again just last week when I had stomach "flu"...the doctor was skeptical and wrote a script for Zofran anyway, but the meclizine worked SO much better for quelling the nausea. I generally think that drugs do more harm than good but when you're lying on the floor unable to keep down food or water & something (meclizine) relieves that, it's like a miracle."
