2-3 hours after the GFJ is best. There are several papers on the subject. It works too....or so I've heard.
Swim can totally related to being paranoid when smoking. So much so, Swim had to give it up, because it wasn't even the slightest bit enyoable, because Swim was paranoid, and would do NOTHING but worry about lifes problems, ect. The only thing it helped was for an afrodesiac, and Swim's girlfriend of 6 years just left me this weekend, so what's the point, of an afrodesiac. I say ;eave it alone if it makes you feel that way. Good luck
