How long until my energy and dopamine regain

I have now been off of pressed adderall (methamphetamine) for 3 months. My overall well being is better. I knew that I couldn't continue taking them as much as I wanted too. Started using them as a replacement for a 2 year long cocaine addiction. In the beginning I thought they were legit adderall. Later come to find out they were infact pressed methamphetamine. I was a weekend cocain user and always went thorough the lows of the week but eventually my mood would get better around Tuesday Wednesday. I'm concerned that my brain will never fully come back and this anxiety makes me think about using again. Any insite would be helpful. Just seems like my energy crashes mid day. I do go to the gym 4x5 times a week. Any suggestions would be great. Thank you
