Caffeine OD. I am positively experiencing that right now. Have not had coffee for such a long time, & I had a big mug today. Jo is 4 months old today & he pulled a stunt on me through last night. He was probably feeling nostalgic & drank like a newborn. In addition to that, for the 1st time, he chatted & chuckled aloud (very loud) to himself for a good 45 mins from 5am. I could strangle him, but how could I have the heart to do that? He's soooo adorable. Plus, he's so tubby, I can't even reach for his neck. Double chin's in the way.
