Don’t waste your time. I had been prescribed Meclizine for a vestibular disorder, but the vestibular symptoms went away long before my medicine ran out. When I read that it was called 'Dramamine II' and was supposed to have the same effect, I thought perhaps I could use it instead of Dramamine to trip. After 16 pills - 25 mg each - nothing happened. I just felt a little light-headed, nothing even close to a 'trip'. If you have some laying around the house, just save it for any time when you're feeling vertigo or general dizziness - it's great for that. But for tripping? Forget it.
