’m not feeling a lot of misery now
That is good and I don't care HOW you got there! That should help you relax more doing the exercises.
It still sounds like you are looking at it logically, only thinking, instead of SEEING.
Once you learn to SEE it, rather than analyze, things will change. It takes some practice and yes, when it happens, it just happens. Doing these exercises increases the probability that you will drop out of thinking and into LOOKING and SEEING.
I encourage you to just keep LOOKING and doing the exercises. There are others I can give you and you can always repeat what has already been done. There IS value in repeating them until you SEE. (My seeing at LU happened via looking for the place where butt meets chair (Believe it or not, I, too, was on a couch and never thought to make the distinction.It did not matter.) Could not find it. It took a while, but then it all clicked.
Did you say you have read Gateless Gatecrashers (free PDF under Resources here) or Liberation Unleashed (for purchase on Amazon)? Those are good for examples of others who used the same process to see no self. There are people who cross the Gateless Gate just reading those.
It's only a little tricky - in the same way that we don't want to do The Work with a motive, we don't look for no self with a motive. You have a ton of curiosity, which is the ideal attitude, but the motive of wanting to release suffering is actually causing you to cling to it in a way that does not help.
It may be that you would do better picking one exercise and sticking with it for a while, if we have the definitions and analysis out of the way for now.
