Nausea medicine!

Okay so I'm 15w6d and my doctor put me on phenergan which I took for about 5 days and all it did was knock me out and I was nauseous again before it was time for me to take another pill. So I just picked up my new prescription today. He gave me diclegis, which is suppose to be the best. I just took my first dose so it's not yet in my system. So I'm just wanting opinions on the meds and maybe what else can help me with the nauseous cause it's not getting any better.
