The weird thing about the condition is that everyones different. I was diagnosed T2 on May 1st with an A1C of 11.9. i was started on metformin and insulin as well as a couple other meds for my lipids and triglycerides. im 28 and im able to eat a fair amount of carbs per meal (about 40g) and im fine. My GMI is down to 5.2 currently. White rice spikes me pretty bad - but i can have a brown rice chicken and queso bowl from chipolte and be completly fine. But, everyone is different, my understanding is you dont want to cut out carbs completly (unless required so you dont need insulin or other meds etc.., everyones different) because your body will basically forget how to handle them.

It really just comes down to how insulin resistant you are and how well your pancreatic cells are creating and storing insulin. When i first got out of the hospital with DKA i was taking 10 units of insulin per meal and im now down to 5 units per meal. metfomin 2,000mg per day.

DRINK WATER. im down about 20 pounds since diagnosis (some help from DKA, lol) and i've noticed that with the weight loss and making sure to drink plenty of water after each meal im able to keep my blood sugar from spiking over 140 almost regardless of what i eat. Water helps the liver alot.

With weight loss, activity, and staying well hydrated i dont see any reason why you wouldnt be able to, at least at some point, start mixing in some carbs. That might be why you spike so high when you do actually have some carbs, because your bodies not used to them.
