Oop, I sidetracked a little. Well, I've noticed several people who have said they wished they never tried DMT/aya in the first place. By saying "a point of no return", I meant the motivation/optimism sort and that I may never feel this way (motivation wise) again after first contact with Aya. I believe I'm past this now, for sure - On some nights within the last few months I have just been so eager to have a taste and see.. what all the buzz is about. 

haha, of course. I was being too specific. If I have the choice to avoid a something that's possibly addictive, harmful, unnecessary then I will avoid it. Although there will be several times a year where I drink a nice cup of caffeinated coffee. MMMMMMMM, my favorite.
