For the past week or two every time I lay down I feel sick to my stomache. It does not matter how I lay or where. After a min or two I get that gross taste in my mouth and my stomache starts feeling sick. I want to vommit but nothing ever comes up. Durring all of this,I also develope a lot of saliva. Has anyone else had this problem? I would really love to know what is going on. Thanks!
