Weight: Gaining It Or Not

I went to the doctor the other day for sinuses. Tis the season.
The only time I check my weight is at the doctor's office. I don't own a scale. I was certain I'd gained five pounds. My clothes just weren't fitting like they used to.  I stepped bravely on the scale and discovered I hadn't gained a pound. Must be the combination of gravity and age. Anyway to say I was surprised was an understatement. 
To recover from the shock I treated myself to chocolate and pizza.
Anyone else out there suffering from the tug of gravity?
