That's why I just have duplicates of everything critical. My spare tube, a patch kit and a spare Epi-Pen live in my seat pack and do not come out. If I have a flat (touch a wooden honey dipper, I've never had to use my Epi-Pen), as soon as I get home, I patch the old tube and hang it on my seat so I won't forget to put it in the seat pack as soon as the glue is cured.
Same thing with my travel kit - toothbrush, toothpaste, deodorant, pill bottles, other essentials just live in the kit. If I didn't have a dupe of everything in a permanent place, I would forget it.
