I usually spend around 30 minutes to one hour per day on dl.
24 hours. IV drip.
The better question is how much time off DL. Other than sleep.
Whenever I'm not reading to the deaf, throwing a party for 50 of my closest friends, planting trees with amputees, mountain climbing in Florida, cutting hair at the local lesbian homeless shelter, sewing puddly draperies or rescuing shut-in Yorkies, I'm on Datalounge.
