@AndBreathe Thanks for tagging me on this, as I'm always glad to help
@debs g, My route from Insulin, back through gliclazide, to Diet & Exercise, was slightly different as I was on Basal & Bolus insulin (Lantus & Novorapid) rather than a mixed insulin like Humulin M3, so I could tune my doses to give a tailored exit strategy. I trimmed off both insulins then went down to just basal thencame off to gliclazide, first 80mg then 40mg then finally 20mg. I found that using the 40mg tablets, in conjunction with a pill cutter, allowed me to get dosages right! (One thing that I found was that in the final days of minimal gliclazide, a 20mg (half a 40mg)would give my pancreas a "kick2 that made my responses improve for several days!
@debs g,
I would suggest that you get yourself onto a basal & bolus insulin regime and this could allow you to tune out the spikes in your B.G. and then you may be able to get back to gliclazide, if not at least you may be on insulin with more flexible control.
Good Luck!
