Oh my gosh!! I'm so sorry for you and your son.
Good for you in keeping on the proper path-- its so tough, I understand. Yea, the "shaking"-- I understand.

I also feel as though I've been electrocuted-- fierce buzzing throughout my body, jolt of energy followed by feeling wiped out-- do you get that way too?
I think what the others have said is great advice...... I'm not much good for advice when I'm right there with you-- sorry.
thinking of you and my heart is with you and your dear son.
