| Chinese food is hard to bolus for... I usually guess about 100g for Chinese (depending on what I eat), but I do have my insulin to carb ratio pretty fine tuned. I also take Symlin whenever possible if eating over 30g of carbs.
One of the ways I found easiest to fine tune that ratio is to eat pre-packaged meals that do not have a lot of protein or fat. An accurate carb count can help you nail down the insulin to carb ratio, which may be different at different parts of the day. The closer you get to the correct ratio, the more carbs you can eat without skyrocketing.
Then there is also the trick of taking your insulin about 10-20 minutes before you eat. That can help with the post meal bg spikes. |
