Started the Xifaxan yesterday and was no worse. Last night, could not sleep, sweaty. Got up this morning feeling sicker, nausea, bloating. Started my regular routine of Alprazolam then Simethicone/Mylanta liquid. Mouth and throat extremely dry. Was afraid to, but took another pill this morning. Will this pass? My husband is mad and said we are not going to ER again. I feel so sick.
