I'm a week into my first insulin, having been put on Lantus once a day, have gone from 10 units to 25 units in 5 days and my bloods are still ranging from 9-27, spoke with nurse today to ask about rapid insulin to bring the spikes down. She said to continue on the long release as its harmful to reduce my bloods too quickly.
Its the rollercoaster blood sugars that your micro vessels (in eyes and kidneys) do not like as well as the toxicity of raised blood sugars so I'd concur with the above. Slow and steady via a diet (and insulin if necessary) that you can sustain has to be the way.
I'm afraid I agree with the others, best to do a gradual lowering to minimise eye issues. Plus there is the practical issue that you need to increase insulin gradually so as not to overdose.
