I used a dictionary to make sure I had an adequate description for you.
Let's take a look at two words, shall we?
adj. ex·treme (ik-strem)
2. Being in or attaining the greatest or highest degree; very intense: extreme pleasure; extreme pain.
3. Extending far beyond the norm: an extreme conservative. See Synonyms at excessive.
n. hun-ger (hnggr)
a. A strong desire or need for food.
b. The discomfort, weakness, or pain caused by a prolonged lack of food.
2. A strong desire or craving: a hunger for affection.
Yeah...that would be it. Uh huh..."extreme hunger" would be the most precise way of identifying what this is that has overcome me the past few days.
Strangely enough, it seems to overtake me almost every two hours. I'm not talkin' "I need a snack" hunger. I'm talkin' "Pass the meat and potatoes!" hunger, if you know what I mean! I don't know if I remember reaching this extent during the last two pregnancies, but there just doesn't seem to be enough food to satisfy my peculiar, unceasing state of...you know... "extreme hunger."
