Remedies for morning/all day sickness

So I've been given a sample for Diclegis and of course the sample is only 12 and I take two at night which just knocks out my nausea and then I ran out...The next day I was dry heaving and throwing up everything and if I didn't even eat anything I threw up stomach acid (sorry tmi) now I was able to get a second sample because insurance will not cover my prescription and we all know how expensive it is 😒 but honestly I'm now noticing the Diclegis is like starting not to help I only have like 4 pills left and then I'm done for again...Does anybody know any home remedies or something I can do to help..Honestly feel like a walking zombie
