Feeling drowsy or after meals?

Have you ever felt drowsy, tired or like you have low blood pressure after eating meals?

I usually feel this way when I have a lot of carbohydrates in my meals,  and it seems that my body needs a solid amount of time to metabolise, so I get really tired and sometimes cold, since my body is using up the energy to metabolise the food. 

Things that I do to prevent this or help, are; I either try to eat less carbs in the evening, or I have a cup of peppermint tea or fennel seeds. If you find that your blood pressure drops, you could add some honey or agave to the tea. Salt also assists with low blood pressure, so another idea is to add a little more salt to your food – of course you need to check with your doctor or nutritionist if it is ok for you to use more salt in cooking. 

In general, you would also ideally drink more water and exercise more. 

Do you have low-blood pressure? How do you deal with it?
