Hope you feel better soon Karbea, that sounds awful :(
Ambassador, I'm sorry but your salad dressing handbag has made me laugh-I do have a handbag tip that might help a bit? I keep everything in my bag in plastic pencil cases (I have quite a few), you can buy them in different sizes from ebay)
-Hands. Mini hand cream, nail file, orange stick, small bottle of clear polish or topcoat, tiny round pot with those all in one polish remover wipes
-Essentials. Phones, USB phone charger, debit card, house and car keys, work pass, £30 cash in notes, five pounds change in coins for car parks, comb and mini mirror
-Medicines/emergencies (this one is very full, but has no more than four of each tablet or thing!) paracetemol, ibuprofen, sudafed, Strepsils, immodium, senna tablets, Karvol, Calpol sachets x 2, teething powder sachets x 2, plasters, earplugs in a small case, single use twisty thing of saline solution, tampons x 2, mini tube of antibac gel and probably a few other things I've forgotten!
-Snacks. Small bag of almonds, small bag of apricots, Nakd bar, Earl Grey teabags x 2, pack of chewing gum
-Make up (worked this out as everything I'd need to repair my face if I ever cry at work, or my luggage gets lost when I'm flying and I need to go to a meeting before it arrives!) Travel pack face wipes, 2 x sachets of facial moisturiser from a magazine, cheapy Boots cucumber eye gel. Tiny pot (5ml?) with enought foundation for me to use it two or three times, concealer stick, mini eyeshadow, black mascara, eyebrow pencil, very thin flat pot of blusher and small blusher brush
Then I have a couple of others for when I'm travelling that just live in my cupboard until I need them-
-Passport, emergency credit card, European health card, company emergency phone line card
-Travel-(in case luggage gets lost and I need/want to shower before it arrives) sachets from magazines of shampoo and conditioner x2, shower gel x 2, body lotion x4 (they never give you enough in a sachet!) spare pair of knickers, travel size deodorant, cheap toothbrush and mini toothpaste tube, mini pack antibac hand wipes
I started to do this when the baby got interested in my handbag, to keep baby slime off things, and now find it's a great way of being organised and only carrying the stuff round that I need. It does also mean if I have a drink in there and it leaks, that the handbag stuff is protected (and I guess it would work for salad dressing too!) and that I never lose stuff in my bag.
Just realised that it might work for other people too, will write the above into a blog post when I get a minute :) Hope the bag wasn't too badly damaged!
