Do a little experiment. The things that you use daily, always keep them in the same place, even it means you have to walk across your home to get them to use them. For instance, your tobacco... always put it in your night stand until the moment you are going to use it. (Or somewhere else.)

Keep things in consistent places. If they are still going missing despite the rules you have made for yourself, then it's one of two things: 1) You have a severe short term memory problem; or 2) Something really is taking them.
