Hope you recover soon.

Angharad,
Sorry to hear your are under the weather, here is a quick cure.
1. Take your right or left hand, place the little finger tip on a desk or table or kitchen counter.
2 .Spread your hand straight up, with the thumb pointing up.
3. Fold the other three fingers toward the palm of the hand.
4. After this is done, this represents TWO fingers.
5. Find a LARGE glass that will fit this the distance of the little finger to the tip of the thumb.
6. FILL the glass, with the TWO fingers showing at the side, with an Alcohol beverage of your choice
Although it does work best with either "Buffalo Trace" Straight Kentucky Bourbon.
As an alternate, you can also use "Jack Daniels" Old #7.
As you live in Great Britain, I suspect a good Scotch Whiskey would work equally well.
Unless Wales has a similar type beverage available that I am not aware of :)
5. You now have a TWO finger drink and no-one can prove you different.
The cure is you will not care how bad you feel or whether you can actually feel anything until about 2-3 days later.
Hope this does make you feel a little better and brings a smile to your face
