They used ketamine as the anesthetic drug in my ''treatment,'' so I came out a bit out of it for a short period when I woke up, which at times was fun even thought its suppose to be a serious situation I think. It can be scary though because once you've experienced it once or twice you know that once you start to feel that ''feeling'' you will be knocked out in the next few seconds and there's nothing you can do about it. It did not work for me personally, but I heard stories about it working for others. One thing I will say though is that it was a safe environment and the people were nice.
