I used to think I was immune too, but IDTS anymore. Like, the very first time I used quickhappy, I got good effects, but the next 5 times...nothing, then the last time, I got the effects again. I say, just keep trying them. Some people claim they work better with all lights off, laying down, possibly with an eye mask on, just concentrating on the beats. Also, some people say they work better with just web surfing or posting, or doing whatever you normally do, like it nothing special, just with no other sound (like the tv or music) on to distract you. I'm kind of at a confrontation between the 2 myself. The first time with quickhappy, I did the whole lights off, laying down thing and it worked, the next 5 times...nothing, and the last time, I did the web surfing/game playing thing and got the same effect as I did the first time I took it, so IDK. Hopefully some of what I said makes sense and helps you out, a little bit anyway. So, I hope it does eventually work out for you and you have some good experiences.
