I'm at a family reunion and suddenly I feel like I'm going to pass out or have a seizure. I am not epileptic. 11 years ago I did meth and it made me have these mini convulsions like things. I haven't done a single drug in 11 years and quit alcohol and cigarettes 3 1/2 years ago. Does any one know if its possible to have those same convulsion type things even after being clean for so long? I worry about it a lot and it scares me.
