what kinds of fruits do you eat? i usually stick to apples as you can eat them right away, pears its always hard to get good ones and you have to wait ages for them to ripen. those 2 actually arent recommended for vata though, they say to eat the really sweet high Sugar stuff like mangoes, papayas, cherries, grapes, peaches, pineapples, melons, raisins. i have been eating berries lately too since i got a good deal on some at the market. mangoes are awesome too but hard to get good ones.
crash as in i had no energy, lost a ton of weight, and got really sick. i have had those dark circles under for a long time, that is a sign of a messed up liver.
what grains and beans/legumes are you eating? brown rice? lentils? which beans? how often do you eat them?
i know 100% i have parasites because i've seen liver flukes come out in the toilet with my own eyes. chances are you do too, as do 90% of the people on this website. people are buying into the candida myth when its parasites that are causing it. i havent had much luck eliminating them all .....through diet, herbs, cleansing, even drugs. liver flukes seem the most impossible of all. you mention gallbladder issues, you probably have stones.
