anxiety and stress
"Had a severe reaction to this medication one first dose including waking in the middle of the night dizzy and disoriented, proceeding to vomit repeatedly, numbness in fingertips and gums, severe chills and then soaking in sweat, and difficulty speaking. Took a trip to the ER. I am sure that it works for some people, but the side effects can be very scary. 



Make sure someone is aware you took it and keeps an eye on you. It is very unlikely you will have a reaction like I did, but having someone in the know will save you some trouble if you do have a bad reaction."
