I am an active meth addict and I am concerned about the possibility of my brain being chronically flooded with dopamine.

This has been really hard to admit. I've been using narcotics for 6 years and I'm now 25.<br><br>I recently got back from rehab and I've been clean for 3 months. Soon after getting back home, I started craving and everything spiralled out of control. I was back to doing drugs before I even noticed, it has been almost 5 months now.<br><br>I just want to know if it's possible for my brain to enter a state where it just constantly releases dopamine into my system or something similar. Lately, I've experienced periods where I feel slightly happy all the time. I feel almost as if my dopamine floods my brain even when I'm not on, at random times, almost as if my brain is "rebalancing" itself. <br><br>I'm scared that if my brain enters a state where it constantly releases dopamine, then I won't be able to feel high anymore. I've noticed this has already happened in a small way after using drugs for years. It takes me much longer to enter a "high" state than it used to, a high being a state where my brain releases more dopamine.<br><br>I am really scared and I don't know what to do. I've been on meth for almost 6 years now. In the past, I was able to control my drug use, but lately, I just get cravings so strong that I can't resist them. I always end up back at square one.
