Uti and morning sickness

I'm supposed to be taking uti medication along with zantac for indigestion. But! Every time I drink or eat something, I vomit it back up. So taking the pills would be a waste. It would just come right back up. I have an appointment coming up next week so maybe they will be able to help. This sucksssss. So hungry. My throat is so dry. I'm producing alot of saliva.
