Watch movies, read this forum. Get a cool thriller book to occupy the time. Go somewhere else - perhaps the mall eegads... an arcade. Drive to the country and do absolutely nothing but look around at stuff I haven't seen and drink lotsa coffee. Go visit a bookstore read a bunch of stuff and buy nothing - except coffee and doughnuts. What the heck, go visit 2 or 3 bookstores, stay active. Go around to all the health and nutrition stores to get an opinion from every clerk in the city on their opinion of the effectiveness of natural sleep aids. Start writing your own book. Perhaps an online blog... (you can do this at your profile here)... Call up someone you haven't talked to in a long long time - go visit them. Get a new boyfriend/husband. Strategize on starting a new business that you've always wanted to... Change the oil in your car. Change the oil in your friends car. Go visit a homeless shelter and/or volunteer yourself.
(and while you're doing all the above, watch all the sober people!)
Lol. That's a start!
