I've been doing some research on this in regards to alcoholic, drug and other types of addictions. Some of the with-drawal symptons described by the people going through them, seem to be moderate to severe. I personally went through symptons such as: feeling physically weak, body tremors, headache's. These are but a few of the symptons. I was wondering if other's here have or are currently going through with-drawal type symptons and how strong are they.
