Wow!
That's a whole heap of starchy carbs there.
Bread at lunch, bread for a snack, ice cream, pasta.....
Is that your normal diet?
Needing water may have meant your BGs were running (unsurprisingly!) high. Do you measure your BG? What was happening with it?
If you could give us some readings we may be able to give you some insight.
You may also want to look at your diet. Your choice, but that diet, taking Glic, is likely to lead to the need for further medication as your Pancreas works harder and harder and probably gets weaker and weaker. Bit like supercharging a knackered engine in a car. Gets a lot faster for a while, but don't last long.
