No this is not anxiety. That "throat thing" is your tryptamine alert. Everyone has one, and each persons alert is peculiar to that individual. It comes on really fast within 5-10 minutes of eatting mushrooms or LSD etc. long before you actualy get afect and come up on whatever compound you have taken. Some people get a warm flush some people get a cold flush, some people get breathless, others get a tingleing sensation on some part of the body. For me, my finger tips swell. Or at least they feel swollen. Your alert is with you for life, get used to it. It is your friend.
I am a clown, nothing I say can be taken seriously. It is my profesion to talk nonsense
