Casa,
Knuckle down, gut it out this time. You're on Day 1, you KNOW what lies ahead in the next few days. You've gone through the SUCK before, you can do it again. Don't do it just to throw it away. Sign that contract and keep it with you. Get some phone #s, make some online/text/phone contacts. Tell your family/friends that you QUIT. FOR TODAY and for every today. Hold yourself accountable. Post roll, no nic, repeat daily. Exercise, load up on H2O, arm yourself with gum, fake dip, seeds, whatever you need.
Bunch of bad ass quitters in May...welcome aboard!
