30 days NC... NOW a craving??? Help!

I have had a rough one today, the worst in a couple weeks at least.

I haven't had a craving in a solid 2 weeks, and today I have had one on and off pretty much all day. I am 30 days NC today, and instead of celebrating I'm feeling like this. It's quite discouraging,

For the people who have been NC for a long time - how was the journey for you? The first couple weeks were almost unbearable for me, but I plowed through them. I will not allow myself to actually give into the craving, but the fact I'm even having one makes me feel really disappointed in myself.

I know this is a long journey, and 1 month NC isn't really a significant amount of time, but for me it's like a lifetime,

Today I was having thoughts about the "good times" when we were "in love" (which I know were a lie) and the thought of literally never talking to him again with no closure bothers me, I know these people don't give closure, it's part of their game, but it still hurts.

Any advice/encouragement would be greatly appreciated. :)
