@eggs11 - Call me radical, but I don't get excited about Dawn Phenomenon (aka Liver Dump), but then mine has never been too extreme. Let me try to explain my rationale.
When our livers release glucose in the mornings, of course we haven't eaten, so the only place that can come from is our personal reserves it keeps for us. So, releasing a bit of the reserves is a bit like running down a rechargeable battery a bit.
Next time we eat, our body prioritises recharging our liver, so that can have the impact of softening any rise from the first foods eaten.
Of course that's mega, mega simplistic, but for me the liver/battery imagery works quite well.
I'd say if you feel you'd like to try IF, then do it. Trying something doesn't mean you become wedded to it for ever. If you try it and don't like it, or it doesn't help you out much, then you can do something else.
The key to all of this is your meter and how you learn to interpret the readings it gives you. I refer to that as eating to your meter. Don't get too wedded to good foods/bad foods, but go for the foods your meter gives you decent feedback on. You'll never find perfection; nobody does, but it's about finding your compromise between your way of living (including eating) and your meter readings.
As a pre-diabetic you're likely to have a bit more leeway than someone with a higher HbA1c score.
Good luck with it all.
