Acid is like having all the wires in your brain reconnected to other senses. You can hear shit more intensely, see things further away and have your brain make up some crazy ass pictures. LSD is by far my favorite drug in the world, but it can deff change a person. One tab will be fun and safe. If you want to really trip out 2 is always the way to go. Be warned it can fuck with your brain afterwards. I tripped out 2 weeks ago and now when I get stoned i see traces alot. Im not sure if this will pass but every other time ive done acid Ive never had it happen to me days after. Give yourself about 24 hours to trip, come down, and rest your body. Sleep after a trip is key to resetting your brain. And Vitamin C is good for the body after a trip
