My doctor said that I might have an inner ear imbalance -- BPPV -- and noted that Promethazine would actually help with the dizziness.

That sucks. That means I will either take Promethazine for dizziness, or ondansetron for nausea. Fun. Taking both I feel wouldn't be a good thing.

Any severe interactions with them? Anybody have experience with benign paroxysmal positional vertigo?
