7 lbs lost and I never want to find them again

I am on day 6 of The Plan and it is unbelievable to feel the transformation of my insides.  I am not going to lie, the first 3 days were hell inside of hell.  I never had the food that I was eating, the tastes were beyond foreign to me and a little scary.  I couldn't snack, making me want to snack even more.  And lets just say, it was the wrong time of the month for me to start a crazy diet.  Nonetheless, I made it through the 3 days and successfully lost 4 lbs.  That made it all worth it.  Seeing the numbers FINALLY budge after hard work made me feel so fulfilled and worth the exhaustion, aches, pains, migraines, irritability and bitchiness (sorry family).
I am now happily on day 6 and feel so full of energy and excitement.  Something that I haven't felt from the inside in a very very long time.  I say inside because to me, thats the most important.  I have the energy to workout, I have the energy to clean the house, I have the energy to run after my daughter and at 9pm I still have the energy to write this blog.  I am sleeping better, I am not feeling bloated and I've only worked out once.
My parents started it today and my mom is finding it really hard - same reasons as me, but add in the fact that she drinks maybe a sip of water a day.  On this diet, and generally for good health, you should be drinking half your body weight in oz a day.  I am at a little more than 2 litres a day, and for me, thats no biggie.  For my mom, she would rather eat dirt than drink a glass of water, let alone 2 litres.  My dad is making it happen, in his usual style.  Its a scientific way of looking at your body and at food, and for my dad that is right up his alley.
Day after day, I am so interested in this diet because it is teaching me about myself.  Teaching me to expand my food repertoire as well as why the heck I have been eating "healthy" foods and gaining weight and feeling like crap.  I am excited to continue and see what the rest of the tests have in store for me.
