I was the same way for quite a while. Lucids are more likely in later REM cycles. So I'd sleep an extra 1-3 hours to get more REM cycles. But as the OP laments, that eats into your day. You probably want to change up your approach. Instead of spending 1-3 hours trying for more dreams, limit your sleep to 8 hours and then spend 20 minutes to make more thorough DJ entries. Or schedule a WBTB or WILD attempt into your normal 8-hour routine, which will only add maybe 10-30 minutes. Basically, work on using your time efficiently while limiting your total time in bed to fit your real life schedule.
