Why did you stop? It seems you did, but since it made you feel excellent, it seems strange to “choose to stop”.

It’s not an innocent question: Gains and feeling extremely well and confident and serotonin-boosted are only useful if it can be sustained in life. The two alternatives are: 1. It pumps you but tires you very fast and you get fat down the line, and your overall life is ~obese (seems to happen to way more people than one could assume), 2. Only the change produces this feeling, and change cannot be sustained forever.
