Congrats man, it's a lot different than you'd expect hey! Especially spanning 3 lifts over the whole day.

It's never a good idea to do a weight cut leading into the first few meets unless you already know that you're going to win only if you compete in the lower class. I don't know anyone who's cut into a meet or done a water cut and not regret it the first few times.

It's a huge variable that only needs to be introduced if you're going to be competitive only if you do or you're at a higher level. For your first few local meets you should eat into them to perform as best as possible and get the hang of competing. I'll be doing my 4th meet in a couple weeks and I'll only be dieting into my 6th, even then I'll probably get below the weight then eat into it and lose some water the day before.
