Thanks for this information Sid, I'ts just that I thought that havings eaten an hour before I would have had enough energy. I usually go out for about 40 mins walk and get mildly out of breath nothing to strenuous though.
Whilst not disagreeing with the above comments, I think your routine could be fine. I don't think Sid was suggesting that if you go for a walk after eating you should have a Mars bar first; I think his was a general comment about what might happen if you exercise strenuously without eating. You might not be getting a liver dump at all. You say that you have your meal, then exercise, then test; you get high readings. What you don't know is wether or not your readings would have been even higher if you DIDN'T exercise. In other words your exercise could be succesful in bringing your BG down from even higher levels. To find out, you would need to run a few tests, having the same meal with and without exercise and testing after the same period. You can't rely on a one-off test though; we differ from day to day. Also, you would need to know what your reading was before eating so you can see if the RISE in readings is more or less with/without your walk.
Even if you do get a liver dump, I think the benefits of the exercise overall more than outweigh a temporary rise in BG. In my case, on diet only, and I think the same would apply with metformin, I can go really low after exercise (I've recorded 3.8) without getting a liver dump. I think that perhaps, although I have no proof of this, liver dumps don't occur as frequently as we might think on reasonable exercise levels, unless perhaps you are on potentially hypo sugar-reducing drugs (NOT metformin). Maybe some people test and see a high sugar level and deduce a "liver dump" when they were high anyway. Liver dumps occur normally when BG goes too low, and our problem most of the time is the reverse. Again, I stress that I'm NOT referring to people on BG lowering drugs, and that metformin is not a BG lowering drug as such.
