If you do not put some effort into improving your levels, then you will end up injecting Insulin.
You must be eating a lot more carbs than you realise, and that is the root of the problem. If you could give us an idea of what your meals are like, we may be able to help.
The Glic' is basically turbo charging your Insulin production, and the more anything is pushed to it's limit, the quicker it wears out, or eventually fails. Hence injecting Insulin as you can no longer produce enough for yourself, a long way off but better to avoid altogether.
By reducing the amount of carbs you eat, you are reducing the amount of Insulin required, to handle the sugar level.
( hence the need for extreme care whilst taking the glic', monitoring levels so as not to go too low)
As the levels drop and the Insulin level drops, then Insulin resistance improves, so again less Insulin is needed. When reduced enough the glic' should be able to be kicked into touch,
BUT only when your doctor says so.
Don't concentrate on sugar, concentrate on carbs, they ARE sugar.
Below is a link to a chart which i think graphically shows the effects of what we eat.

I suffered from terrible neuropathy, with burning feet in bed (excruciating), and electric like shocks. As my blood sugar levels dropped, they have virtually disappeared. I know when my levels are a little higher at bed time because my feet get hot, but hanging them out of the covers cures that.
As for your dislike of losing your hair, mine went along time ago. My laid back thinking was the more i worried about it, the quicker it would go.
