I Am Excessively Tired After Eating, Anything. It Can Be

I am excessively tired after eating, anything. It can be a piece of candy or a small meal. I will fall asleep without even knowing I did . I will wake up several minutes to hours later. I have done the one other time, when i was having some issues with my blood sugar. This was resolved by eating more fruits and vegies. This is not normal, not this extreme tiredness and falling asleep without even realizing I have done so no matter how small the meal or snack, so please do not say it is. Despite my attempts to research this topic out I am reading the same answers continuously, as if there is no other possible explanation for this to occur. If I was not experiencing this before and am now having this issue, then in my mind something is not right. Please if you do not have enough info or do not know why indicate as such so I can provide further info or take my search else where. Thx for or help
