The solution is to experiment if you understand what you are and when then you will cope.
When I am normal 5-8 mmol/li make sure I have some chocolate or other such in my pocket so that should I go low - I just look greedy, also I have noticed that when I am out of my routine I get low or equally high as it is out of my routine.
Not sure if this is of any help but I think the answer is to try and read your moods, body and work with it if you are low then eat if you are high then exercise, not excessively just see what works and go with it. My Dad who also has type one walks up and down stairs when he is high and just has a bar or chocolate when he is low it's kind of a ballance not one we always get right but, the better you know it, the better you can cope, unfortunately there isn't a silver bullet it is just experience -anyhow we are all out here worrying and kind of coping, not sure if this helps, hope it does.
