I don't think that you can stop it or slow it down.Three things come to my mind that happened before my awakening.One of them was this pain or should I say tightness in my root.I couldn't straighten up the upper part of my body after sitting down, I was stuck.It felt like a lower back pain but it didn't really hurt.After this, I got this intense stomach pain ,vomiting for 4-5hours at night and I was sure I was going to die. Then after this stopped, I could hear this internal screaming and of course I had no idea what it was and I ignored it for like 5 months.So,there are certain things that will happen before an awakening and you'll just have to watch for it.
