carb up question

[scruples]

i finally did a carb up day today after feeling pretty flat in the gym this morning in the hopes of improving future performance... i've been following crum's diet for about a month now and have lost nearly 20 lbs... and i've had plenty of energy this whole time up until today... my question: is it common to feel tired on a carb up day, especially if this is my first one in a month? i haven't carbed up really hard, just a little extra dextrose in the form of sweet tarts and a shake with a little whey and some dextrose powder... oh, and a couple of slices of dried mango... but i was so tired this afternoon i had to take a nap (which is pretty rare for me) anyone else go through anything like this??

thanks...

happens all the time, eh.

Release insulin which releases extra seratonin, which makes you sleepy. And it does seem to be exaggerated or worse when you've been low-carb for a long time.
