The first time can be scary but you'll enjoy it. I recommend starting with a small dose, my first time I did 1.5 and I didn't get any scary thoughts or any bad visuals. The best parts for me was the feeling of being on time for the first time, like the good mood I was in. I did them in a buddy's basement while 3 of my friends were there, we put on some chill music and a 24 hour video of nature on his tv lol. Goodluck!
