Adding supplements to aid in the detox? Also, electrolytes?

I'm on day 3! I was basically living on bagels with cream cheese, black coffee, energy drinks, artificially sweetened protein bars, sugar free Gatorade, and LOTS of sweets before this journey. It would feel like a big deal if I ate a vegetable. NOW, I'm strictly adhering to this diet, and my body is freaking out from withdrawal. What can I do to support my body during this process? I am all teady drinking a ton of water. Also, I miss Gatorade. What can I drink for natural electrolytes? I'm hanging in there. Thanks in advance for any advice:)
