Jack, congrats on your great decision. Day 2 sucks bad, but you will get through it - hang in there. Honestly Day 3 sucks bad too, but you will get through that also, you have to. It's a matter of life or death. You can do this, and I promise, it does get better. You will never be able to let your guard down for the rest of your life, but you will feel better soon. Proud to quit with you today, brother!
