Yes Sniper, ALL THE TIME. I think you do have to consider effects of medication.
Also you can start thinking up ways of making it less likely that you will lose stuff. Like have you got a wall of tools with each one drawn around and then put them back when you finish with them like peoples dads do? do you have a place for everything and everything in its place? I don't because when i have energy I want to get on and do things, not waste time tidying and sorting. But then I spend ONE HOUR looking for something which, exactly like you said, turns up somewhere you never were. And another thing, when somethings really lost you have to look through the rubbish bag. Its never IN the rubbish bag but if you dont look through it first you will never find it. Dont ask why, these are the rules...
