When I'm sick things are kept as basic as possible. I get as much help as I can for things like grocery shopping and do internet shopping if all else fails. I stay in pj's to minimise washing and to stay extra comfy. Ds gets to watch tv, play on the computer, whatever he wants with minimal limits when I'm really sick. It is hard work, but you do get better, although it may seem like it will take forever. I was sick and so was my 5yo ds and my 7mo dd a few weeks ago and we all were stuck at home for a week. Thankfully dh didn't get too sick and helped where he could.
As for the fluvax. It's a must in my book. The 'real' flu will knock you flat for 2 - 3 weeks and if you have Asthma it could land you in hospital. A cold can make you feel rotten and give temperatures and a cough and contrary to stupid TV ad's that suggest you soldier on, it can make you very sick for a week - 10 days. I have the flu vax every year. There are 'flu like illnesses' that mimic the flu and I got one when I was about 23 and I was sick for 2 weeks and my parents both got sick and had to take a week to 10 days off work completely and then went back to work eventhough they weren't 100%.
The fluvax won't stop you getting a cold, or a flu like illness, but it will stop you getting true influenza and even if it's only one less illness for you a year, it's a nasty one and it's one you would appreciate avoiding I'm sure!
