JJ thanks, yes that does make some sense. Another question, my blood sugar levels drop really easily, do you eat anything on the way along. I have tried the gels, twice, I guess I need to give them another go. I did not like the taste of them, I did not like the texture of them and finally I did not like the stickieness of them, ie I got the stuff all over my fingers and else where. In one word UCK. Over to you.
