I was also addicted to high-crabs and Sugar until 3 months ago when I started to use serotonin and GABA supplements. Since than my cravings completely disappeared. However, I've become lethargic, anxious and depressed; although Depression is also a result of several, recent hard-to-bear events.
It seems as if I'm in some vicious circle-one problem solved another occurs-so.
But somehow, considering my circumstances, that link that Crisb1 sent, really makes sense to me: ... when your life is seriously out of wack ... best thing is to withdraw.
