New theory,

I had to put this in...some scientists now believe that addiction is caused by a lack of seratonin in the brain. They used to think that drugs destroyed seratonin because when addicts were tested, they showed a lack of that chemical in the brain. So they came to the conclusion that the drugs/alcohol destroyed seratonin...HOWEVER, nobody ever tested them BEFORE the addiction.

So now, many believe that some are born with less than normal seratonin, so they are attracted to the substances that will give them what the brain needs...of course. Health food stores sell 5-htp and l-tryptophan, which is natural seratonin. It is easy to test brain chemistry, but I'd bet that just taking it will tell you if you need it...if your brain already has enough, it won't affect you much. If you really need it, trying it will change your life. Tweet
