The last two days I have had a couple of very low readings and feelings of being light headed. I take two metformin SR one with lunch one with tea ( I only eat twice a day, my fasting reading in the morning is 6-7 so if I have breakfast I go way over the norm even if I take a tablet with it, most I have is tea and one belvita biscuit) This is how I control my readings in the morning it is not a problem for me to do this. I have atablet with my lunch say 1 piece of burgen bread and corned beef a bit of salad and a packet of crisps. I may have a blue riband biscuit after something like that. This keeps readings well under 7.8 after 2 hours then I will have another tablet with dinner say a stir fry with veg and chicken and noodles then again for pudding a small dark chocolate bar or a zero jelly and fruit and cream as an example. my readings would be about 7.5 with this after a couple of hours. But the last two days I have had a light headed feeling late afternoon tea time and on taking readings found them to be 3.8 Thursday and 3.4 Yesterday This is too low isn't it? this amount of food means I have gone down 2-3 dress sizes in a year but I dont feel hungry. They say you cannot have problems so I just quickly ate something in fact both days I had a biscuit and the feeling goes away after a while. Do you think I am eating enough? I thought maybe not I tried to eat breakfast to see if that helped but today I got up reading 6.7 had a slice toast a tablet and reading two hours later 6.9 OK but that means its getting to lunch time I had 1 slice bread, 1 slice corned beef i tablespoon potato salad 6 pringles and then a dark 2 finger kit kat. 2 hours later I was 9.9 (because no tablet presumably), I am not happy with this. The timing of the tablet for me seems important one at lunch one at tea and no breakfast seems to be right for me, but I am worried about these lows are they dangerous? I do not take insulin only Metformin SR
