Is there a way to regain serotonin levels? i abused mdma couple years ago, and am worried about long-term effects. particularity worried about 1 night where i did alot. i havent done it in years, and dont plan on doing it. serotonin levels depleted?

Serotonin levels may go down temporarily but they return back to normal levels on their own quite rapidly. So I would not worry about the past activities mentioned by you.

First of all, it is not really possible to measure serotonin levels related to the brain. Serotonin is an ubiquitous molecule present throughout the body. Most serotonin is actually involved with gut. Even the notion that since SSRI drugs block reuptake of serotonin is inaccurate and an oversimplification. Bottom line is that your brain is not depleted of serotonin. Good idea to layoff the MDMA.
