Ah - tetanus shots. Some vaccines are suspended in a water solution, which disburses quickly; others in an oil solution, which takes a few days. OTC pain medication works wonders for tetanus shot pain.
I bought a couple of heavier ankle weights and have started using those three times a week. And Jack's been complaining of extra weight, so he's now on board the weight-loss wagon. Makes it a lot easier for me, I'll tell ya.
Also, after years of looking, I found a pair of killer jeans in my goal size (in the right proportions - no huge gap in the back of the waistline and they actually go to the waist. Do you know how rare those are???) So I have even more incentive.
