Thanks for the answers, but has anyone had the experience of an allergy/intolerance causing such a sleepiness? I heard Martine Navratilova talking about cheese causing her a similar problem!!
My mum always said when I was growing up that cheese gave u nightmares if you ate it in the evening? Don't know whether she's right or not as I have a dairy allergy so don't eat cheese!!
Lettuce is definitely a soporific not sure why tho?
If I eat too much of anything containing refined white sugar, it makes me fall into a deep sleep, very quickly and gives me a monster headache the next day.
Kim A, it's me again! I seem to be follwoing you around! I feel very tired after refined starches like white pasta, white rice, wheat, bread etc and I know this is a common thing, but I can't give them up. Also get very sleepy after coffee, believe it or not!!
