| I'd say it's more likely than shaking, it could have lost it's effectiveness just by being too warm in your pocket. While shaking it may cause chemical bonds to be broken, I have a hard time believing you were doing enough moving around to shake it this much. If that were the case, the insulin in my pump would never work!
