First time on LSD- I feel weird?

Hey guys, so I’m 57 minutes into my first LSD trip (100ug). Did my research, got my music on, wrapped up in a nice blanket like a psychedelic burrito… but my heart is racing like I just dry-scooped a pre-workout, and I’m grinding my teeth like I owe the Tooth Fairy rent.

Is this normal? Am I about to transcend into another dimension? Or just become an anxious, vibrating entity for the next 8 hours? Send help (or good vibes).
