I'm about to loose my mind

It started off as a major case of "the grumpies" for Lindsey and I. But now my kids have been totally "off the hook" for 4 days and it's getting a little old. I can't figure out what is causing it. They are like their hyper wild dye induced selves, but I really don't think they've had any food dyes. We were all home together until they went back to school today. No restaurant food, no new foods. Tonight was the worst. They are all so wound up, loud, impulsive and silly it makes me really wish I had some Ritalin. Either that or something a little stronger for me lol.
