Nausea/Vomiting
"This medication is amazing! For the past year I have been feeling nauseated and sick, so my doctor prescribed me promethazine it takes about 15 - 20 minutes and I feel a lot better. The only thing side effect is the extreme sleepiness I feel afterward. I will go to bed and sleep for hours. Lately I also developed some anxiety to feel nausea and I take half a 25 mg pill of promethazine in advance and usually it works great. I&#039;m a little tired but I can still function. This medication works amazingly!"
