Have you used ritalin, adderall or any drug that increases dopamine after crashing?

Has any of you used ritalin, adderall, cocaine or any drug that increases dopamine or norepinephrine?

What has been your experience?

My experience with ritalin (after propecia) is the following: my penis became hard-flaccid, it shrinked a lot, veins became much more visible and colour also changed. Also it caused pain.
Mentally it caused panic attacks, suicidal thoughts and many other problems.

Sorry, maybe this topic could be merged with this one:
