Phenergan (25mg)

Okay, so I had been having awful morning sickness, not being able to hold anything down for three days. So I went to the dr and they prescribed me 25mg phenergan. It helps SO much with the all-day sickness but I feel drugged all day long. Like high maybe? It's very strange. Anyways, I was wondering if anyone else has experienced this? I've seen online that other people get like this and so they take a half of a pill, but what do you guys recommend?? I hate feeling like a zombie all day long.
