Your problem is a genuine chemical addiction. You are causing your body to release endorphins that affect the pleasure center of your brain just like antidepressants.

There are medicines that can help you level out your urges. Your problem, being so extreme, needs to be treated like other addictions. Wellbutrin is a drug commonly used to help people calm their urges. But, you really need to be evaluated by a psychiatrist to determine if there are other contributing factors.

IF you are unable to find a psychiatrist or can't afford one like a lot of uninsured people, there are some holistic approaches to the problem. A supplement called SamE helps a lot of people get themselves centered. It helps pick up their mood. If you want to try something more direct, look into Salt Peter. It is very common chemical. (Used to make gun powder) But you should get the pharmaceutical grade. You take a dose when you start filling the urge. It will kill your libido. It's been used and abused for a very long time. Still, I think you really need to see a professional to get the best treatment. Good luck!
