Breeze, if that happened to me then it might be due to my needing a change in my carb ratio for my evening meal. I take 1 unit of Humalog for every 6 carbs I eat. That is called a 1:6 carb ratio. that gives me a high two hours after breakfast so I use a 1:4 ratio which gives me more insulin. That solved my high BS after breakfast problem. If I had lows after my evening meal I would try a 1:7 ratio, which would involve my using less insulin and result in higher tests in the late evening. I don't know how your gastroparesis works into the equation since I don't have that problem. I am just thinking that it may just be a matter of too much insulin for that time of day. Many insulin users do not seem to realize their carb ratios can vary throughout the day. Carb counting with carb ratios is much more effective in controlling BS levels than a sliding sccale.
