milk is bad

Please don't drink milk. The quantity of mucus you reported almost certainly points toward a past excess/intolerance to dairy.
Also, the milk nowadays is not the milk that was around during Shelton's time. In his time there weren't masticating green juicers, either.
I strongly suggest Watermelon juice or watermelon; if too sweet - half or 3/4 water in it. Or just small bites, well chewed, of Watermelon or melon... or any other fruit except banana-type of fruit (too dry, to sweet). Or 1/2 water 1/2 Celery juice. Or 3/4 distilled water 1/4 carrot juice whenever you decide to rap it up. You can put few drops pf lemon on top of anything above and, in my "intense" opinion, any of these would be 1000 times better than milk (unless it is (obviously not cooked) mother's milk of a woman who is healthy, was fasting for years and is raw vegan).
