I'm a bit jumpy at the minute. Diet fell off a bit of a cliff at Christmas, and my sleeping patterns are out of whack, and I'm having some ridiculous hypnogogic jerks. But I'm slowly getting back to where my anxiety levels were before Christmas. I've resigned myself to being anxious for the next 7-10 days, and I feel quite comfortable with it, as I know if I stick to a simple diet I'll be feeling okay soon.
I echo Titi's advice, and give the same advice to myself. No alcohol (medication doesn't work if you drink), no refined and simple carbs, and no high sugar fruits. Excercise without overdoing it, none of the intense burst stuff which has become trendy in the last few years. Basically keeping under control (or keeping regulated) all the things I'm (for various reasons) hypersensitive to.
So my diet at the minute, and for the next week or so is revolving exclusively around:
Potatoes, baked
Salmon
Turkey, grilled
Bergen bread (less hidden sugars than white and wholemeal)
Low sugar fruits, mainly raspberries, blackberries and blueberries
Porridge
Avocados
Mushrooms
Peanut butter
Soup
Cottage cheese
Houmous
Unsalted nuts
Seems a bit dull on the face of it but they're all very versatile. A turkey and avocado sandwich is gorgeous. I usually find the taste of cottage cheese on it's own absolutely rank, but with a little bit of pesto or smoked paprika it's alot more palatable.
