Dear Stillmyson, I know that us Mom's all have given some pretty straight feedback about relapses and how addiction warps our children's thoughts, feelings and actions. I also have rescued many times hoping that this was the LAST time and that my son would return to me. My advice is this. Let both your Mom and Step Dad and your sons Father know what is going on and educate them to the signs. With meth use, you will see very enlarged pupils, extreme energy followed by lethargy (when they are coming down) and lack of appetite. If your son relapses, he will resort to taking things and pawning them for money. Please make sure you keep close watch on your valuables (and your family's) and also see if your son is willing to start attending meetings at his new location.
I wish you the very very best and I hope your son is ready to quit and not return to the lifestyle and despair of addiction.
Hugs,
Teresa
