Yep, me too between weeks two and three. It passes. Take Rainy's advice and go for a walk or distract yourself in some way...whatever way you can. After a ton of reading (most of which can be found here) I realized that it does take awhile for you/your brain to learn to process emotions sans booze. Little things (or nothings) seem huge, huge things seem numbing...other times stuff just comes from nowhere and you cry and feel like hell. It's all part of the process. I still have those moments (I am almost 3 months sober) now and again but they have receded greatly. And now I know that they are "normal," I just consider them part of my brain's healing process and am grateful for the healing---even though I may feel awful in the moment.
Sixteen days is awesome, you're through some of the worst parts of it! Hang in there, it feels so, so much better the further away you put yourself from that bottle. I never believed it was going to be true but, happily, it is.
Big hugs to you tonight!!
