Quitting Caffeine with a Starved Mars (Understanding the Five Elements Course)
Also, caffeine, especially coffee, depletes zinc(male health, aka Mars) and B vitamins(energy and nervous system/brain, both Mars related) needed for energy.
As you're cutting down on caffeine, maybe switching to oolong or green tea and decreasing that as well, maybe not having it every single day, you could take a zinc supplement or eat more zinc-rich food.
Unfortified, undebittered brewer's yeast is a good Mars food and can replenish the B vitamins that caffeine depletes. you can put a table-spoon or two in smoothies or oatmeal.
It is a bit bitter when taken alone but mixes well with other flavors. And the bitterness is part of the nutrition. Don't get "de-bittered" brewer's yeast, as its has lost some nutritional value and is usually "fortified" with synthetic B-vitamins to try to make up for it.
If you still keep using a lot of caffeine though, good dietary nutrition and supplements get wasted as caffeine also competes with the absorption of, and doesn't just simply deplete, the nutrients.
It has become well known that heavy coffee consumption depletes our "Jing" or essence (shukra or a kind of ojas) and commercial herbalists are selling expensive zinc-rich Jing tonic herbs like He Shou Wu in powder form. But they sell it to you by telling you to mix it in coffee to counteract the loss of vitality!
That is a waste of medicinal herbs and caters to lazy consumers going on a supplement bing while still trying to feed their addiction. And it just confuses the body more.
