When i see a blood sugar trending up I over react and take a little bit of insulin to avoid having my blood sugar in the 250 range. Thats sounds good but usually a few minutes after taking the insulin the up arrow goes away and my blood sugar levels out around 150 like it did today around 4pm. I will then be low and the roller coaster ride begins. Going from 150 to 60 every couple of hours. I need to trust myself and my diet moving forward. It is easier said than done however, it is tough to see that up arrow.
