i would say it would probably be ok, but the beach could be a problem. first time i did it i had 2 strong sugar cubes and it was AMAZING. you'll probably be fucked up, but as long as you don't worry and think positively you'll probably be fine. but, waiting until you know what your in for may be a good idea before running out to the beach and by that i mean wait like 2 hours, see if you feel cocky or paranoid and choose the beach accordingly. for me i was always wicked confident on acid even if peoples faces were changing constantly. have fun, be safe, and it'll be life changing
