Sorry for being serious, but have you considered studying part time? If you're just after a degree in the first instance, this might be an option. You will be giving up evenings and/or weekends, depending on which institution you study at, but I preferred this to distance learning as I found the discipline of having to attend lectures more beneficial, and I also preferred the interaction with lecturers (cue edit...) and most of all, I enjoyed meeting fellow students and the pub!! In my last job, one of my colleagues was doing the same degree through the OU, and she really did feel like she wasn't being supported throughout her studies, but horses for courses, and all that.
I have experience of the best and worst attitudes of bosses to whom you tell your out of work activities.
