Hi and Welcome to our little forum! 
Actually, it’s quite extensive! But, we are all here to help each other out!
I know you will have an over abundance of information presented here but you will have the same in experience from other users! There are much more experienced users than I that are glad to share there opinions and suggestions with you.
I’m so glad you have that experience in reading others be it tone of voice, body language, etc! That is very useful when trying out mones! You can check out how to find your sweet spot and Tisha exquisitely describes how to know a "hit’’ when you see it! Check them both out on the links on my sig below.
For the stress and artistic frustrations that can come about I’d suggest you look at this thread: \HERE (Mones that will clear up brain fog!)
At the very least it could lead you to other mones that could be more in tune to the self effects your looking for.
Now, I would still recommend that you try out Instant Shine as it has given me a good bump in retrieving thoughts and memories. Not what I got IS for, but it was a pleasant surprise of a self effect!
For P’s and MX’s, I’d suggest you try out some of the Commercial products first, get a feel for them, then dive into the advanced molecules! C’est mon opinion pour vous pour réfléchir!
Let’s see if this makes sense:
Espérez que vous partagerez avec nous vos expériences et aventures avec le mones que vous choisissez! 
Welcome again and hope that you will share with us your experiences and adventures with the mones you choose!
