Sounds to me like you are not having trouble giving up analogs, you are having trouble giving up the social ritual of the going outside with buddies and doing the tribal smoking thing.
I had trouble with this, too. If I took the e-cig out, I got too many questions and ribbing. I wasn't part of the tribe anymore, chatting and smoking. I became the object of conversation and I didn't like it, even when it was positive conversation. It didn't feel like the ritual smoke break at all, which is what I wanted - not the cigarette.
So, I wrote about it here, and got lots of advice, the biggest being, keep taking the e-cig outside and just push through the questions, teasing, and comments. That took a couple of tough days, but now everybody is used to seeing me with it, and it just stopped and now we are back talking about the weather and stuff. Normal.
