umm I have so many different aids I dont know where to start.
My specially designed legs up wheelchair I couldnt do without. Before that I had a cane chair which was highly beneficial (like a cane which folds out into a chair so you can sit at checkouts while waiting your turn).
My wall clock also has the days of the week on it so I can check what day Im in at the same time as I look at the time (a must have thing on a clock when you keep confusing days).
I use a shower chair with a a stool in there too for my legs up while showering. I have lots of support rails in bathroom.
A cooling pad for both mattress and my pillow (this is great in warmer weather as though they help as long as it isnt too hot without being put in fridge, they also work great on hot days if put in fridge first for a few minutes. (mine is one of the phase shift kind of ones with a type of gel in them which absorbs body heat.
I couldnt do without my electric blanket to warm up my bed when its cold (though It makes me ill if I try to sleep while its on).
A book I brought in which by looks and title, looks like an ordinary quite boring novel (you shouldnt have "passwords" written on the outside cover of your password book nor should this book look interesting) but it hides ones computers passwords in it (has section for web addresses and the one I have also has a little section in each to put notes for the websites to).
This is helping me a great deal in clearing up the mess I used to get into with lost passwords due to me forgetting them all the time. Now they are all together secretly hidden in a book which wouldnt draw anyones attention.

stool on wheels. I made this actually recently when my computer chair broke by then ripping the back of it off and I then had a stool the right height for my legs on wheels.
Timers on my hose taps outside (before I got these I'd sometimes accidently leave the hose or sprinkler on all night).

A birthday card organiser (this was a recent buy of mine of for years now I hadnt been doing the birthday thing as its been too hard for me to organise). It has an alphabetical order parts throu the book in which you can write down peoples birthdays (like one would write down names and info in an address book.. a page for each letter of alphabet) but it also has a pocket in it for each month.
This pocket is so one can buy birthday cards for a whole year for family and friends and fill them in and then put them into the pocket for what month the persons birthday is so you can be organised for a whole years worth of birthdays in advance. Great for u if your ME is very erratic and may not be okay to be doing a card when the persons birthday comes, this makes sure that card is there and already done (if you forget to give it to the person or dont end up seeing them, its still there for the year after).
On subject of birthdays.. I also as my mother used to do when I was growing up.. keep a birthday box/chest where I buy throughout the year things I come across on sale which I think someone would like for their birthday or xmas and put them into this. So whenever its someones birthday if Im going to be seeing them, I just go to this box and go throu it to find a gift.
