Do you actually know it's LSD?
Probably not.
First find a reputable source, second make sure they're legit. Find somebody that knows a thing or two and has eaten said doses or has tested them. Find out the ish of what they're mic'd at and what a good dosage might be. Figure out a good place to do them. Sitting at home on ns= not that much fun, hiking in the woods with some friends or seeing a none shitty band = awesome. Try to make a little bit of a plan. IF you don't know much about the world you want to leave yourself some outs. Not having to drive, not having to deal with parents, not doing it somewhere that you're anxious about, not doing it with shitty friends.
If it's print don't swallow it. Let it chill on your tongue for a while and absorb then spit it out. you can let it kick it for a pretty long time. Some of the ink can fuck with your stomach. If you swallow them you might be doing good and all the sudden feel very sick near your peak. If that happens no worries, drink water and chill. If you have to puke, puke. That's what you body needs. If you puke drink water and relax a little bit.
Don't eat a fuck ton. You can't switch of the trip because it's too intense. It's better to have it not be enough than have it be far too intense hours before the peak. Don't eat a bunch more because you haven't felt anything a half hour in. The worst in when you don't feel anything really, eat a bunch more, than soon after feel the firsts starting to kick in hard and realize you're going for a fucking ride. Buy the ticket, take the ride. If you eat them, you're going for a trip, go with it.
The trick was to surrender to the phlow. Just relax and let yourself twist and turn through the world that's opened before your eyes. Embrace it. The more you fight it the worse your experience will be. It's not like feeling sleepy where you just shake your head, throw some water on your face and your back to normal. LSD is a very powerful mind altering drug. It's powerful to the point where it can over power the effects of other drugs.
Watch how much you drink. You may notice you can drink like a phish once tripping. You seem to be superhuman to alcohol. While I generally enjoy some booze on the come up(not that I hate booze anytime) You need to be careful how much you drink. For instance, it's completely possible to drink 26 beers in a night and still be completely functional, then be alcohol poisoning need to go to the hospital mode sick and practically dying when you start to come down. You'll generally do alright with beer. It's much harder to drink far too much. Be careful not to chug a fuck ton of liquor, that can make things bad.
Watch how you store it. Leaving doses free floating in your wallet is not a good thing. Don't leave them sitting out in your car in the sun. Also be careful. LSD is illegal. Very illegal.
Bunk L, LSA, research chemicals aren't fun. Watch what you spend your money on.
Have a good time, be safe, enjoy your ride.
