Hey tree-peony!
Don't want to spoil your good news, but my BGs do a similar thing to your's - rise at 4 hours (not 2). I'm LADA and on insulin. My quick-acting is all used up before my BG rises :roll: My DSN advised me to move my evening basal (Insuman) from night time to evening. It's an intermediate insulin with a good peak action at about 4/6 hours and it now captures my 4 hour rise and stops it. I'm sure you won't want to hear this, but if you can't control the 4 hour rise any other way, maybe a shot of intermediate acting insulin around tea time would sort that for you, allowing you to go to bed with a good level and probably wake up with a good level. Just a thought - don't know if that would be appropriate for you.

p.s. I saw your earlier response to Paul - being overweight does not mean you can't have an autoimmune type of diabetes - it just means it would be even more difficult to convince medics that you are not Type 2. Obviously, you probably are Type 2, just wanted to make sure you know that not all LADAs are slim, so keep an eye on your levels ad go back to your doctor if they don't come down.
