B2Y - Because shopping wipes me out, I break my shopping into parts. On Sunday I make the menu, do the grocery list, get the coupons ready and anything else I need for my shopping at any and all of the stores I need to go. On Monday I do the shopping in the morning as early as possible but like you, by the time I get home it's lunch time and I have very little energy to even make any lunch. There is no way I could even possible do both in one day. Not only is it too exhausting, it is way too confusing for me. Sometimes if I have more than one store I need to go to, I save some of the extra stores to later in the week instead of trying to get all the shopping done in one day. It took me quite a while to find a system that works best for me. If I find new difficulties as time goes on, I make changes as best as I can.
