Here to commiserate - I too find it so hard to balance a full-time job and a study schedule comparable to what so many other LSAT-takers seem to be doing (3 hours a day is just not workable for me.) Sometimes I find it helpful to remind myself that working full time and studying for the LSAT is hard!

I have learned that my best study hours are first thing in the morning, so I try to do 1-2 hours before my work day starts. Then, like so many others above said, my evenings are "free" - I don't feel bad about watching TV or working out. Some days I can barely make it through a drill and others I feel alert and ready - I did a whole PT this morning before work. For me, it's less about studying a set amount of hours a week and more about consistency - I'm a creature of habit so find it really helpful to have a fixed routine.

Also, I do as much as I can during the work day (don't tell my boss...) but this varies depending on my work schedule. I know this is not viable for everyone, but time management and prioritization frees up time for me to sneak in an hour here and there.
