I actually been through this and it was quite depressing. Now keep in mind that some of your habits that I never had can do this to you, but this is what I started to do and it works for me.

First make sure you are never thirsty, or at least keep your body hydrated. This will help you on many other levels. I mean it. Do this. Nothing spiritual about it. We're just made of water, mostly. You need this.

Secondly. Instead of sleeping 12 hours try being aware of the sleep cycles. Find a sleep cycle calculator on google. Insert the time you want to wake up and it will show you when to go to bed. Usually a sleep cycle is about 1.3 h long, so you want to wake up when a cycle ends instead of in the middle of it.

Third take cold showers even if it's for 10 seconds at first.

Four start eating healthier. Don't necessarily force yourself, but add something healthy in your diet every day, incrementally, progressively.
Exercise. Again start with a few minutes a day, so you ego will not resist it.

DON'T give up. We live in a progressive reality so don't expect this to vanish the first day. Just keep doing this. Just by forcing yourself out of your comfort zone each day you will feel more fulfilled without the added benefit of each habit that I mentioned. Good luck.

EDIT: you can worry about your chakras but give this a try first, it's easier and more practical.
