Not sure if I have the answers, but having quit two days ago, my eyes are red as can be, and I seem to have an acne breakout over my face and a red rash across my chest.
I have read somewhere that the bloodshot eyes will gradually reduce, but it takes about 6 weeks until they are back to normal.
Great that you have made the decision to quit, and as you know, it does take a while for the body to repair. All the best for success!
