My diet got very cheap when I figured out the high protein, fat rich western diet caused my problem. Baked potatoes, fruits, veggies, can be low cost. Food is expensive when it's making you feel like shit and going right through you based on the picture you put up. Celiac disease is also something that could be happening based on your symptoms...simultaneously with liver impairment and other food intolerances .
I won't send you to a bunch of herbal remedies on here. I got better from a 3rd world poverty diet, based on lots of potatoes, yams, broccoli, fruits and veggies etc. It's a plan for anyone's pocketbook. These digestive and liver issues create poor judgement, confusion, negativity and a head filled with false dilemmas. I can't change my diet for this, I can't do this because I have to perform these tasks at work etc... Liver Cleansing involves kicking gluttony to the curb and seeing what almonds, steak, cashews, oils, all have in common.
I am 25 and I got called a student several times because of this mess when working at high schools...now everyone compliments me on the weight gain since march though. I can count so many personal and monetary losses because of my shut-in ness. I'm amazed with how diet can have this simple effect.
