I came home from work tonight and was relaxing for awhile and my legs became very restless. I haven't slept much this past week and so, I took an Ambien to help me calm down and hopefully, get some sleep. Well, I got up after a short time after taking the Ambien and it felt like something was caught in my throat or I had a "film" in my throat. Then, all of a sudden, I started gagging and then threw up in the sink four times! Shortly after that, I threw up two more times. What could this be?? Sorry for the TMI. Thanks
