Common problem, I'm about 6 weeks in vaping and yes I chain vape while working at home. However, I'm down to 4mg juices and find that to be just as satisfying, for me it's more of the hand to mouth habit and the nic doesn't seem to be a factor. Have you tried scaling down on the nic? I'll probably move on to 0 nic soon...
If you ask me, that's great. I'm starting my third week and chain vaping at home is de rigueur. I have at at least another month's worth of carts and juice at 16mg before I even begin to think about going to a lower level.....perfectly OK with that. Are you waaay better off chain-vaping than smoking even half a pack of analogs? Yup.
