38 days to go and having a diet dilemma

I won a pair of Ripcurl cargo trousers on e-bay last week which arrived at the weekend. In perfect condition and just what I need for the trip, and a bargain at just £3.17. Getting them on is not a problem, but bending over or sitting down is definitely not an option at the moment. So with Christmas round the corner, the diet is going to have to be geared around swapping my preferred beverage (pint of carling) with something less calorific - vodka, lime and soda maybe... do they sell that by the pint? I also ordered a pack of two spare camera batteries this weekend so I am almost there with the equipment list too, just need a few more SD cards. Dad and Janet have lent me their handheld luggage scales to ensure I don't exceed the 15kgs total luggage limit. Here is David's recommended packing list;

1. Camera body(s)
2. Long lens - most people take up to 400 or 500mm for this trip.
3. Shorter zoom lenses
4. Batteries
5. Chargers
6. Memory cards
7. Storage device or laptop
8. Lens cleaners
9. Instruction book
10. 1 pair shorts
11. 2 pair cargo pants
12. 3 T-shirts/cotton shirts or similar
13. Outdoor shoes
14. Sunglasses
15. Fleece & waterproof
16. Hat - for sun protection
17. Toiletries
18. Binoculars
19. Malaria prophylactics

Laundry is done for us every day and nothing smart is required, so in theory, two sets of clothes is all I will need.   My new book has arrived too - "Tick Bite Fever" - David Bennun's account of growing up in 1970's Kenya, ('A hilarious memoir...Enchanting and amazing', The Daily Mail .'Laugh out loud is an understatement...a wonderful insight into life in Africa from a two-foot high point of view, witty, touching and above all affectionate', The Press Assocation .'Tick Bite Fever itches with mordant wit - there's at least one turn of phrase per paragraph that gets among your ribs like a feather duster. An excelle

nt memoir', Uncut Magazine).  It should help to pass the time on the eleven-hour flight to Nairobi and put me in the picture a little before arrival. It was either that or a book about the murder in the Masai Mara of wildlife photographer Julie Ward back in 1991 which I think I will save for the flight home!
