You are doing the right thing.
Research Ketogenic diet- essentially you are putting your body through a cycle of ketones- as long as you aren't certified type 1 diabetic ketogenic diets won't hurt you so don't get worred when you see the hype.
Your body is going to stop using glucose as its energy form and switch over to ketones- it will burn fat instead. This will happen around day 3. You will bed depressed for the first few days, maybe a week, 2 at most. Then you should feel better, maybe even great. I have been through shit like this myself. Its essentially carbohydrate withdrawal.
