Crying it out

With my first child we did the crying it out method at 10 months and she cried for 3 minutes and went right to sleep and never had another problem. I'm feeling very tempted to try again with this child but I feel like it's to early. He turns 5 months tomorrow. I'm just at my wits end. I'm losing my mind. He's up every 2 hours most nights. I dont want to do it anymore. I'm legitimately losing my mind. But I also want to do what's best for this little demon child and I know crying it out is looked down upon a lot of the time. I'm all about attachment parenting in every other sense but I also havent slept in 5 months. Any alternatives?
