Too much sugar

Lori
Ok I'm 13 weeks pregnant already been in and out of hospital several times and have been struggling with dehydration. Now I'm dealing with excessive saliva and nausea . To make matters worse I can't seem to get my sugar levels right. I can't stand water right now and everything I drink seems to have so much sugar. I have severe acid reflux so can't drink most juices and I'm completely miserable. Has anyone else experienced these problems
