Kendall, just to focus on one part of your post (the evil ice cream!)...I agree with the suggestion for BALANCE. Being a Libra-Scorpio cusp, as well as having a Capricorn rising and Capricorn moon, I find my body reacts negatively if I do not try to achieve balance in my habits.
Yet, I am a sensualist, lover of beauty and pleasure, and balance need not be about asceticism...
An example, in terms of food which is one aspect of this discussion: I eat basically the same breakfast every day: fresh fruit (in season and organic if possible), coffee (a blend of organic dark roast and decaf beans and chicory) with cream, and whole-grain toast with organic butter.
Could I do without the butter and cream? Of course; but the other aspects of the meal are healthy, and it gives me pleasure and starts my day off right.
If I want to cleanse or lose some weight, I might adjust my morning meal for a while (fresh fruit with organic yogurt and herbal tea, usually); but eventually I go back to eating what works for me.
Sometimes on a Sunday I might have crumpets with peach jam, or bacon and eggs. If I ate this every day, it would not be good; but occasionally, it makes me happy and does no damage.
I think enforced denial of pleasure causes stress; and this is far more detrimental to well-being than the worst of our vices...
Many oldsters out there claim a whiskey and a cigar every day keeps them young...
Now if I could figure out the proper sex equation as it relates to all this...
