Meth as I had problems with Meph and I reckon it probably feels better and is more addicting.
LSD and mushrooms as am scared of having horror trips and not recovering propely. DMT as it sounds like a life changing drug which I'm not sure I'm ready for.
at the moment
LSD - couse i need to fix some things in my life before i'll try it (it's THE drug i want to tray!)
DMT - i think it's just to powerfull for a newbe
Botfly - I know where you're coming from with the horror trips - do them in the right place, going into it with the right mindset, and you'll almost 100% certainly have a good time on both psilocybin and LSD - Setting is most important I've found - do it at home with a very close mate who brings nothing but good vibes - stimulating, calming music and lighting, incense/nice smells, good drink and food.
Seriously - don't be afraid - that's what "the man" wants, so you don't reach your true potential, they can be beautiful is hell to trip on and infinitely useful for seeing things from a different, more positive perspective.
IMHO I reckon that DMT is a chemical that you're never really ready for, and if you think it would be too much for you, then it's probably a good idea you do it.
Life changing is the right word - it speaks
to your mind,
from your mind, and gives a tremendous feeling of confidence and calm.
Do it, it'll be over before you know it, so it's a lot easier to reintegrate too.
