I'm in the same boat as OP kind of, like, I miss my commute, and seeing my team and being able to talk to them. I work in support, so I also like having the demo units of our equipment that I can work with a client on. But, I'm a creature of habit that packs the same lunch every day, takes the same route to work, and working from home has thrown my routine into a blender. Also, I live in a small house, and my bedroom is my office now, along with my family constantly pestering me, and my dogs barking at every sound they hear. Once we go back, I'm probably going to do the split 3 office, 2 home though, but for now, the best way I can describe it is that there's no separation of church and state with work for me, so WFH is frustrating.
