Vertig
"I fly often but this last trip I woke up the next day with dizziness anytime I lowered my head.  Difficult since I work on the computer all day and meet with clients so I am up and down all day.  My doctor prescribed it 3 times a day and that is fine as I am on the 5th day and still get dizzy.  I wake up a lot at night feeling like I have to relieve my kidney&#039;s.  This is more often then before I took meclizine HCL.  I do have dry mouth but no real side effects. "
