Wren, stock up on some hard sweets of your choice, these are great for sucking on when you get bad taste in your mouth. I didn't figure out that until a few cycles in.
I second Malt on planning some nice things for week 3. (You didn't mention the interval between chemo, is it every 3 weeks, which is very common). I always meet friends on week 3, usually have about 2 coffee morning/lunch/dinner planned. This is key to my sanity. I love having these to look forward to. To keep having fun is a must. A good laugh and a giggle is great medicine.
I've attended concerts, theatre, etc during chemo. I walk with friends (on fine days only). I do try stay out of crowds during week do, but when the DDs have something on , I go regardless of the state of my immune system. I didn't pick up anything at any of these events. Though, I recommend staying away from sick people if you can at all.
Also re nausea, take the pills as requested, even if you don't feel nauseous. Must easier to stay on top of it than make it go away once you get it, especially on the first cycle. You may be lucky, and not have much nausea. But if you are unlucky, there are loads of medication to deal with it, just let your chemo nurses know immediately.
Actually, there is medication available to handle most if not all side effects. Constipation,sore mouth, sore eyes, sleeping tablets... Don't suffer any SE in silence, ask for help. Those were my SE, everybody is different...
Be aware that steroids make it difficult to sleep. Take them as early as possible in the day. And if sleep is a problem, ask for sleeping tablets. I only gave it to sleeping tablets on cycle 5. The difference between getting enough sleep and not is unbelievable. I was stupid to wait so long. Often there are just a few days per cycle when you need them.
Loads of water. As much as you can drink really. I down quite a few pint glasses a day in the week after chemo.
Sky plus or download some decent tv/films for the days you don't have a lot of energy. I was lucky, didn't have too many of these days.
Consider getting a cleaner, if you don't have one already.
Batch cook when possible. Stock the freezer for any low energy days.
Let key friends know you are starting chemo. Accept their help in making life easier, or having fun days outs.
Keep a diary of how you feel and any SE you are feeling. Usually each cycle will be similar, and it will help you predict how you will feel in coming cycles (though SE for FEC will be different than for Tax.)
Last of all, it is very doable. You just plough through it, and will be out the other end in a matter of several months.
Good luck!! And let us know how you get on.
