Non-addictive stimulant? Maybe it isn't chemically addictive, but all stimulants have the possibility for psychological dependency. Trading one dependency for another is not what I would consider to be progress.
It only has a noticeable stimulant effect in the beginning, after a few weeks you can't tell a difference and it just becomes part of routine with the same anti-depressant benefits. Whatever small risks you're assuming are far outweighed by the rewards.
