Need Help with Lows

I use a 1:15 I/C Ratio for meals and use .15 units per hour of basal (probably so low because I am very thin and insulin sensitive and still honeymooning). I am on the omnipod as well. My 2 hour reading is normally about 90-110 but when that 3 hour mark hits after a meal I almost go low daily. I have been trying to anticipate the low by snacking 2 hours after a meal to avoid going low. Would you suggest I use a higher ratio for bolus? I suppose most people don’t go low like I do once a day. Can you really find the correct ratio that at 2 hours and 3 hours you are 100 and DO NOT need to eat anything else. Thanks

Is it every meal, or is this a certain part of the day?
Test it out by reverting to small numbers: eat the smallest number of grams you can bolus for, bolus, and test at 1, 2, 3 & 4 h. Do at different times of day to learn if you need a different ratio at different times of the day. You probably need some protein with your meal to convert to glucose later than the carb content of your meal.
Yes, you can find the correct ratio, but it may be different for different times of the day.
Remember, if your BG is low at 4 hours, then it’s basal that’s likely to be too high.
