Do i split the dose ?

[CR741]

Hey, i was wondering if you could help me out.
I have been experiening the problem of later meal rises at dinner. I have my meal on a normal reading and then 2 hours after it drops lowish, or a mild hypo. Then it rises when i check it less than 4 hours later. I dont want to increase my units as i will go low 2 hours later, but dont want to reduce as i will go high by 4 hours, so does this mean i must split the dose? my meals are not with lots of fatty foods such as cheese, but it still rises later and i dont know why. The foods are not all really low GI either so im not sure. if i do split the dose, would i half it or only take off about half a unit? and when how long do you wait oi take the rest? sorry, i'm not sure, i never had this problem before and do not have it with any other meals.
Thanks

Hi you do not say what your high/low levels are also do your meals vary from high carb or low carb also if your excersise varies all variants of these will affect your levels.You probably know the ideal bm reading is between 5 and 7 so if your levels rise or fall dramatically outside these limits you may need to speak to a dieticion or visit your diabetic clinic to see if you need to change your insulin type or dosage.
I have been T1 for thirty years and now regulated my dosage according to my diet and excersize.

Possibilities that come to mind.(you are on a pump? your profile says both pump and MDI but I found a post saying you were about to go on one)
For the meal, it might be that like many of us the meal is larger than earlier in the day and takes a bit longer to absorb. It may not completely contain just low gi foods but the overall composition of many mixed meals can be quite low. The insulin acts rapidly before all the food is absorbed
You could experiment with a dual wave bolus (where you give some insulin up front and the rest over a set period of time or a square wave where it is all delivered over a set period...different punps have different names) I read somewhere that one of the US pump gurus (Scheiner I think) says that dual waves should be used for almost all boluses
It could also be that you need a slightly higher basal later in the evening, you would need to do a basal test to find that out.
