Those 'spacey' pockets of time are hard to explain. Easing out of them can be tough, being snapped out of them can be traumatic, and then there's the days that seem consumed by them.
Yeah...once I went on the ADD meds, I became more "tightly wrapped" overall, but even after almost 22 years at my day job (to give one example), I still get "rusty" after a couple of days off, and forget to do basic things, and find it hard to get into the work mindset. Though from what I hear,
most people find it hard to get back to work after time off!
