Any one had TOO much breast milk come in!?

I’m now 4 days pp and I woke up in a huge puddle of breast milk! My milk came in on day two and it came in with a vengeance. My baby drinks maybe a fourth of what is available on one side and I keep trying to pump the excess to avoid mastitis but that’s just leading to more and more supply. I know that shouldn’t be a problem but I don’t want to spend 30 min after every feed pumping. Is there a way to decrease supply to a reasonable level and still avoid mastitis? It’s soaking through both nursing pads, my tank top keeping them in place, my shirt, and now my sheets and comforter ☹️. And this was three hours after last feed.

Help!
