Thanks a lot for the replies, guys, I'm feeling a lot more positive now. Thing is, I know I can do it, because I've shown I can overcome cravings before, and I've shown I can stay strong in the face of adversity, and improving my life means so much to me. I woke up feeling so terrible, I imagine I would have binged if I was at home. Thankfully I had to go to work, and although I felt like dying in the morning, as the day went on I started to feel much better.
Thanks for your tips, I'll look at my situation, look at what's not working and see if I can change a few things. And that quote, Rockit, is so true. One day at a time is the best way. How I'm going to feel tomorrow is irrelevant, all I have to do is get through today, and that's my victory.
When I have some time I think I'll start a new journal, begin reading threads on here more often and take in some more tips.
