I'm so glad you're feeling better. One really effective treatment is to have orange juice or a fruit juice, and if you do suffer from hypoglycemia, a tetra-pack of 5-alive does wonders. The reason, as you know, that juice is so great is that it is a liquid and quickly absorbable form of sugar. It will definitely work faster than potatoes or rice, but whatever works for you is just fine
Where you SHOULD be concerned is if you feel pain in your chest, shoulder, neck or jaw, or like you have a sudden onset of flu-like symptoms. When in doubt, just take the juice and a baby aspirin (the aspirin is SO important as a first preventive medication for cardiac incidents, seriously), and call 911 if you have more concerns.
I feel for you - it isn't easy being home with three small ones who rely on you! Do you have any neighbors or moms-groups in the area that you can make contact with? This might ease your mind, some...
Glad you're feeling beter
