I quit drinking with a combination of meditating and exercising in the morning and doing Tai Chi and stuff. Little things like that can have such a big impact on your overall health.
I've found that getting at least 30 minutes of exercise a day is essential to regulating the lower chakric energies. You can sit and do Asana Yoga or whatever all day and you'll still have a frigged basal chakra if you're not exercising regularly. I've heard of this study that was conducted by Ken Wilber's lot that weightlifting is actually biometrically the most beneficial form of exercise, even more so than powerwalking or gymnastics.
