Well I might not recommend your first experience being alone. I'm a pretty experienced tripper and I'll only trip alone when i plan it to be that way, and those times are more of a meditation sesh, centering myself, a kind of refresh button if you will. and I'll take a relatively low dose, usually 2-3 tabs.. Unfortunately, I have no clue about the exact doseage, as I'm obviously not the manufacture. I can also only account for my own body, everyone has a different sensitivity to substances.
I'd recommend hanging with one or two good friends you've known for awhile, guys you trust not to "have fun with you" while you're in an alter state of mind.
Take your dose, whatever you decide you're comfortable with, remember to avoid touching it with your finger tips, because it will be absorbed this way.
My first time, a single hit was just right!
Within 35-45 minutes my buddy and I were feeling an incredible body high envelope us, there was a weightlessness in my chest and limbs, a spring in my step, and trying not to laugh just made us laugh harder. Pure euphoria, but none of what I would call "visuals" just a little bit of that look that everything is "breathing"
I personally LOVE being outside in the natural sunlight watching the trees sway in the breeze, coupled with the slight "breathing" visuals made for an amazing afternoon joking with friends listening to music around the fire pit. (NO FIRE)
Safe travels friend.
