Has anyone went through the treatement that helps with the phsycial withdrawl of nicotine, to stop smoking cigarettes?

My now ex boyfriend did, he flipped out on me
he almost hit me, he raised his arm up
and was constantly flipping out, sleepping for 2 hours, and then I would wake up with him, and he would yell,curse at me for everythign I have ever done wrong, or everthing I do not do for him
and he would have the same conversations every couple of hours for days
with me, or to me,

one day he was so mad at me, for something not vitally imp
and he was all red in the face veins popping out
and he was actually foaming really badly at the mouth

i never seen an adult foam that much from the mouth
wow
and how scary

he was telling me he is the best liar

he told me he loved me so much, would do anything he could for me
would want to spend his life with me

he was crazy, that was hell, I ate a zillion calories throughout the experience, and started to drink , and take some pills because that was the only way I knew how to handle it, I wanted to be there for the man I loved, my best friend, I did not know I would experience hell.

It was hell
and now I wish I did not go through it

because last week we broke up, because he woke me up from sleeping and told me to get the f out of his house, because I do not do anything for him

ughhhhhhhh

i hope he is no longer smoking, after all that
they give you bella donna, some meds, but he freaked the heck out

and I am broken hearted, angry, and now more fat.
Thanks for listening,
