Thereis you've come a long way in two days! The second diet sounds great compared with the first. Congratulations on the pregnancy.
You should probably try to have 6 small meals rather then 3 or at least ensure you are having good snacks which you have listed above. It may also help with the queasiness.
Always try to have protein with every meal/snack, it will help the sugars to release into your blood stream more slowly.
Oatcakes are great, dip into humous, quacamole or spread with tahini (full of good minerals). Nairns now do a red pepper one which is v tasty.
Boiled eggs are great on their own, as is half an avocado with a squeeze of lemon juice.
Cottage cheese on ryvita with a splash of tobasco?
Have you tried 9 bars, bounce balls, nak'd bars?
Ensure you get plenty of leafy greens - rocket, spinach, watercress for iron, calcium and magnesium.
Drink lots of fluids, water, herbal teas.
To ensure your carbs are not affecting your blood sugar massively, swith to wholemeal or rye bread, and wholemeal pasta and brown rice.
Try not to go too long between meals.
Tomorro'w menu sounds delicious!
