Well as mentioned above we all have been through this stage.
My way is to socialize at work place, play squash, jogging on corniche in evenings, planning ways to get out of Qatar every 9-9.30pm... :P
if you have a car.. long drives..
overnight stay on beach, inland sea.. bbq, bon-fire
I wil be out of here in two months.. so my plan has worked.
All the best.
