Are you sure your 2 different 11/25 tubs feel different to you? Same lot number? Do the powder look different?
Been loving my 11/25, never thought it was gonna get this good again. 5/25 I felt but a bit dodgy , same with 10/25 but 11/25 gives a feeling of contentment
I do also have diagnosis as yours although I am quite well or even very good and fast when I am interested.
It was kinda funny it felt a bit like looking into my own mirror reading your text like it could almost have been me, long snd detailed when on the subject.
Good Excelsior is the best I have ever found for increase in motivation boost. The 11/25 has bern really good for my mood as well although I realize that it is also screwing with sleep big time.
By the way I recently reread Tolkiens Ring trilogy and tje Rnts the tree shepherds say that anything worth saying and listening to should take a lobg time be detailed and je Ents stress the importance of not being hasty.
