i would say just chill (stereotypical stoner words) but its true, i used to go for long walks like a mile with a joint the fresh air calms you down and brings on a creeping high that hits you when you least suspect it, just chill, take a couple of tokes walk summore an also listen to music, it just calms you down seriously, also dont do it in a dodgy room, do it sumwer were u feel safe, your room, bathroom or garden, i really like standing in the garden s having a joint and look into the sky.

I love your description of your first time, reminds me of my first time too, im realy baked now but hope the advise helps.
