Storing sugars is what bodies do
No, you can get your sugars down immediately and keep them there. But that's quite a bit unrealistic. Here's my prescription.
1. see your endo. work closely with him/her to find the correct regimine for you.
2. Test 7 times a day: wakup, 2hrs after bf, pre-lunch, post lunch, pre-dinner, post-dinner, bedtime.
3. Start counting carbs and finding your i/c ratios. Accurate bolusing is critical.
4. Lower your glycemic index. The best control is achieved with complex carbs.
5. Lower your food intake at breakfast and after 8pm. These are most likely to screw you up for long periods.
5. Understand your basals. basal is the basic release of said stored sugars. It happens 24/7, but at different rates throughout the day. It is vital you document your 'curves' so you can treat them properly. For us pumpers it means a CGMS or hourly bg testing after skipping a meal. I do it over several days and weeks by skipping every meal and repeating over a few days. Ask Dr. Google.
