feeling really tired after eating the mix??

Is this possible? I've been eating the CC&flax oil (barleans without lignan one) for about a week. I feel that it's kind of heavy. I am using Nancy's low fat one... is this possible that the mix causes my fatigue?
I eat about 3tbsp CC + 2tbsp flax oil + 3tsp ground flax (sometimes I put garlic).

Could I be reacting to dairy?

thanks for any thoughts. Tweet
