Been on the various stimulants for a decade now:

> But taking a small, consistent dose. Does that work?

Typically, no; however, it's context dependent.

> Do you feel you net benefits in life from taking the drug

There are diminishing returns overtime, but there is still some benefit to be had.

> withdrawal and/or tolerance?

Both are real and awful to deal with.

Is it all worth it? I tend to flip-flop back and forth a lot on this.
