Is this behavior considered withdrawal?

[Guest guest]

My son has been GFCF about a month, give or take a day. Lately I've

noticed more clingyness toward me, crying pitifully when I very

gently say no to him, waking up asking for drink in the middle of the

night, more sluggish, tired acting behavior. His behavior isn't bad,

aggressive or violent but he just seems more easily frustrated and

upset. This is a momentary thing too. He's only frustrated for a

minute and then fine. Are these behaviors similiar to ones any of you

have noticed with your children just starting the diet? I'm really

concerned about the lack of energy he's displaying. He's not up all

night or anything, just a couple of minutes. We are using a GFCF

multivitamin I got at a health food store. Appreciate hearing from

any of you here or deblangham@... .
