Writing buddy or group

I'm looking for a person or small group to hold me accountable for writing my dissertation. I'm stuck in my routine of doing experiments and analyzing data and at the end of the day, the last thing I want to do is write. Ideally, you should be working on some sort of major writing project as well, and we'd write in the same space (perhaps the library) for about 4 hour chunks of time 2-3 days per week. It'd be best if you held me accountable for not getting distracted by the internet/nodding off into sleep/daydreaming except for during planned breaks. We can work together to find convenient times, but the weekend, Tues/Thur after 7, or very early in the morning (6-10am) work best for me.

I'm aware that there is a dissertation bootcamp, and I may sign up for that in the future, but I really just need a bit more accountability for now. I'm not looking for feedback or active interaction with my buddy/group, just pleasant and friendly proximity.
