stepping on the scale again after the new year always motivates me LOL

I go through ups and downs with commuting as well. mostly the foul weather and my pure flabby laziness keep me off the bike, and I always feel crappy when I stop. Try to get back into the swing slowly. Ride your bike to the store or restaurant first. Take 20 minutes around the park on a Sunday - it might give you the itch come Monday morning!
