Sound slike low blood sugar. Good advice from previous contributors and on this web site. Quick fix: a couple of jelly babies. Never go anywhere without them - the speed at which they get into the blood is amazing. You look new. You need to test regularly and see how thinks affect your blood sugar and NOT JUST FOOD - it could be exercise, stress, catching a cold etc. At least make a mental note of everything so that you can learen what to avoid or at least see a problem coming a deal with it. Good luck
