I Am Trying To Recover From A Methamphetamine Addiction, And

I am trying to recover from a methamphetamine addiction, and have started taking mirtazapine, I am finding the medication particularly debilitating, highly fatigued constant dizzyness and unable to phocus on any task also chronic anxiety. I have not had a lot of success with antidepressants in the past, have tried cipramil..... which caused anxiety. Zyban for smoking which made me quite aggressive, and i became heavily suicidal after trying Champix for 5 months. I am dealing with some extreme emotional issues as well related to grief after loosing along with my bank account a relationship with a man I believed I loved who turned out to be a sociopath and was using me for my money. i have been trying to give up for 18 weeks. We were using up to 1/2 a gram a day and the longest i have gone without is 11 days. I have been more or less on my own during this whole time and it is taking its toll on me.
