Mitigating Disadvantages w/o Self Control Number

[Captain Joy]

Are there any tried and true methods of mitigating Disadvantages that don't have a Self Control number?

I welcome attempts to sell me appropriate GURPS titles. E.g. it won't surprise me a bit if something in the Power Ups line addresses this.

This came up because I want my to Star Trek Andorians to be paranoid, and the stock Paranoid disadvantage seems to qualitatively fit the bill; but as written, the Disadvantage is just too debilitating. Something like adding a Self Control number might be all it needs, but I'm wanting to make sure I price it fairly and avoid unintended consequences.

EDIT: If you want to see my current solution, jump to post #11.
