You really won't know how you're going to travel until you've started - once you've had the first one, you'll have a better idea of how it's going to affect you and the pattern of it. By all means, clean your house if that's what you want to do as you may not feel up to it during chemo but I guess it depends how much you care about things being spotless. Personally, if I could afford a cleaner, I'd have one :-) . If friends ask how they can help, then it's always good to have specifics so some help with cleaning might be one if you think they'd be up for it. You may want to investigate online grocery shopping if you don't already do so but then again, getting out might be what you want to do. As for what to buy beforehand - as @kmakm says, you may not need everything but it's good to have on hand if you do. Of this list, the only thing I didn't use was the Movicol.
Biotene mouthwash
Really soft toothbrush (toddlers)
Coloxyl with senna
Movicol
Gastrostop
Toilet wipes (it can get a bit tender)
Disinfectant wipes (good if you're concerned about cleanliness out in the world)
Hand wipes
Hand sanitiser
Sorbolene (chemo can make your skin dry)
Decent thermometer
If you're having cold caps, get some baby shampoo and a wide toothed comb. If you're not, you don't need to rush out and spend a fortune on a wig. See if there's anywhere you can hire one if that's what you want to do. And check out op shops for nice scarves - there's lots of YouTube demos of how to tie them.
I had Crown Mints instead of Fruit Tingles - same purpose. I also found that I struggled to drink flat water so maybe have some sparkling on hand. There is a discussion on here somewhere about best meals during chemo. The one thing I found was that what worked during one part of chemo, didn't do it for me later so just be aware of not preparing too much.
Have you got someone to take you to and from the chemo treatments? It's a bore but at least for the first one, you shouldn't rely on being able to drive home. I would be asleep by halfway home - not sure if it was the chemo, the other drugs given, or the after-effects of anxiety. Don't worry - anxiety is normal but generally not needed.
Make sure that you know who to ring if the meds they send you home with don't work well enough. I went through a couple of days of sheer hell because I didn't know any better and it was the weekend. A phone call on Monday sorted out a script faxed to my local pharmacy and all good. For most of us, there's no need to suffer badly but you do need to know what to do about it, particularly given you're on you own.
Even if you're not a daytime telly-watcher, you may find yourself bingeing on it so iview or Netflix is a good investment.
You don't say where you are, but you may be able to access an Encore class. They usually start at the beginning of term but you will need your doctors written okay. Other than that, see if your oncology clinic has any exercise classes they offer or refer to. It's important to keep up the exercise as best you can - it helps get the chemo through your system, protects your heart during it, and aids to recovery afterwards. But don't expect to be able to run marathons. Immediately after each treatment, walking to the letterbox might be all you can manage and that's okay. If you include the region where you live on your profile, other members may be able to steer you to local classes.
Just remember - while this is not fun, it is doable. You will get through it.
