Hello Cakes
Right - here goes all you Stuckers and Knackereds...
Points to note if you are STUCK:
60% fruit/veg; 30% carbs; 10% protein.
Helps the liver apparently. Lemon in hot water in the morning, first thing.
Turmeric, thyme, lemon, garlic, mint.
Supplements: fatty acids - v important. EPOil (first half of month only) and fishy fats. Zinc. VitB. Calcium. Magnesium. Red rasp leaf. Low-dose aspiring
Eat slowly and chew, chew, chew.
Avoid: red meat (esp non-organic), caffeine, alcohol, dairy products, soya products and flax seeds (interesting as these are often advised for TTC). Don't eat when on the run/angry or upset.
Regular exercise but don't swim in cold water. Meditation/yoga esp' good as Stucks are anxious types.
LAUGH. Go on, louder.
And here goes for TIREDs:
Simple food (well cooked so easy to digest): 50% carbs; 30% veg/fruit; 20% protein.
Pulses. Seeds. Green tea. Spicy warming food - cinnamon, ginger, chilli etc.
Avoid: dairy and wheat. Raw and frozen. Tofu. Excess salt. Alcohol (esp beer).
Regular exercise but don't overdo it.
Limit stress. Keep warm. Protect your back and knees (weak points). Try visualisation. Learn to say "No!" (Wow - my DS is definitely not a Stuck.)
Supplements: royal jelly, wheatgrass, chromium, l-arginine, agnus castus, false unicorn.
Phew. Hope that helps, if rather a lot to take in! If you are a bit of both then you can rework the food stats as somewhere inbetween presumably?! 
Oh Maybe - don't be on a downer. You are pg and therefore tired and emotional.
