I have been bi-polar for years. I have anti depressants, but I still have no "go". I was a fully functioning addict. I would go places, do things, have fun. Since I quit doing meth, I am the complete opposite. I hate what I have become. I just want to feel like a regular person. Found something about dopamine. I may be "dopamine deficient" went today and bought some L-Tyrosine. We will see how it goes. Keeping my fingers crossed.
