I have a strange reaction to my epiphanies. When I've cracked the puzzle mentally and it's time to put the code in the text editor, I start getting extremely anxious. No clue why.
Edit: To clarify, I mean anxious associated with "anxiety", not "with great anticipation"
I know the feeling, and the reason why I start feeling anxious in the same way you do is because I know that afterwards I am going to be in a lull again, that I will be bored to tears and will have the hardest time concentrating and getting done what needs to be done until there is another hard part that needs to get done at which point I am flying again...
