Side effects - Alternatives to picking skin/scalp

[paperstreet]

SWIM cannot resist the urge to pick at his scalp while he his busy studying/reading (the purpose of his amphetamine use). Obviously, amphetamine usage can result in the annoying side effect of repetitive skin or scalp picking and swim was curious if any other users have developed an alternative to this. Swim will think to himself... "No matter what, do not pick at your scalp, no matter how fierce the urge is..." but herein lies the problem... it seems involuntary. Swim just finds himself in the middle of scratching his scalp and wondering why or when he even started. Swim also needs to focus on other important things and cannot waste time constantly reminding himself to not pick at his scalp.

Anyways, any ideas on how to overcome this nasty habit? Swim was considering using one of those devices that improves grip strength while on amphetamine medication, but also thinks that he will get tired (or end up hurting the tendons/muscles in his forearms instead) and is out of other ideas.
