Hi. Carb-counting is very easy and the Carbs & Cals book is often suggested reading. Many of those starting Bolus for the first time start on a ratio of 1 unit of insulin to each 10gm of carb; I started at that. The book or other websites can guide you on the carb content of typical food portions. My DN gave me a pretty leaflet with portion pictures for 10gm carbs. If you aren't sure what your ratio is then go a bit under on the insulin shots until your meter checks after 2 hours show whether it needs to be increased. Some find they change the ratio for each meal/time-of-day. I keep the same ratio for myself at around 1.05 units to 10gm carbs.
