Hi pumper,
Firstly your Carb Ration may not be correct. Also what you eat reflects how it will release glucose into the bloodstream. A food with a high GI will release glucose quickly and then chances are you will then go low. If on the other hand you eat a low GI food it will release it's glucose more slowly and hense reduce the fact that you would have a hypo. I would suggest you have a word with your dietition and read up on it on the internet or buy a book on it and study it.There are so many things that can change the way everything reacts that it's difficult to pinpoint any one thing. Your Carbohydrate Ration is the first thing to have a look at. Sometimes that changes frequently and you should be aware of that also. Do you weigh your food or do you guess carb content?
It is difficult to keep blood sugars within range. If for instance you exercise you would need to adjust for it. you can also give a dual wave bolus or square wave bolus. It takes some adjusting and experimenting to get things right. One thing is for sure. Things will never stay at one thing or another and there is constant change, i.e. weather conditions, exercise taken, food taken, worry, aggravation, illness. All these things can affect you blood sugars and many more I haven't mentioned. You won't ever get perfection but you should strive to achieve it. Plenty of fruit and vegetables every day and good exercise and in the long term it should help you avoid problems in the future.
Some people swear by low carb eating. It might work for you and is worth trying also. That or low GI (Glycemic Index) foods would be your best bet. Perhaps someone else might have better ideas. Trial and error can go a long way to solving this. I wish you well in your endeavours.
