Jan,
I am only 3 months into this and my initial hba1c reading was 97. I too hate medication of any description - and made that very clear - particularly the 'laxatives' you now know about.
I have been well looked after so far by the NHS, but they have left me alone (so far) in terms of medication and 2 and half months later my level is down to 53 - with further improvement expected by the 3 month + point.
The three key elements I was given were a good healthy diet, regular exercise and lose weight. Points 1 and 2 have helped me achieve point 3! .... All of which have helped so far.
You will be given a lot of conflicting / contradictory advice, but do what is right for YOU. This site are very keen advocates of Low Carb High Fat diets and self testing ..., but as you will be aware there are other views / sites and approaches.
Just for the record I am eating far more healthily than I did (but that wasn't difficult), and whilst I am 'Carb conscious' I do still eat the 'dreaded four' - but in moderation. Equally (and I know I will draw flak for this) I do not test test test as some do. I MAY at some point in the future, but still not right for me currently my call, my choice!
That said there is some good information you can get from in here - I have.
