oatmeal making me sick/lethargic? IS it gluten?

[Billytk03z]

when I eat my pre-wo meal of oats and whey I start to become immediatley tired, fatigued and bloated... Is it possible that oatmeal contains gluten or is it just the oatmeal itself....? If I eat a bowl of cheerios and drink a scoop of whey I am fine pre-wo... so what gives.....?

thanks for any input...
