Does Phenergan make you drowsy for a long time?
I was so tired yesterday afternoon, so I took a nap for about two hours. When I awoke, I felt like I was going to throw up. I took a bubble bath and some Phenergan, and crashed about an hour later. I slept for about twelve hours and woke up, and now three hours later, I'm sleepy again. Could this be side effects of Phenegran?
