Hi folks, thanks for the replies and apologies I've taken so long to come back.
By lowish carb I mean between 150 - 200g per day with around 120g being my evening meal.
Yes I have have tried LCHF (between 20-50g daily) and very successfully as well. If you look back my posting history you'll see that. On LCHF I was able to wean myself off all medication and have an HBa1c consistently between 5.2 - 5.9, got back to my lifestyle obsession of weight lifting and felt great.
All went to hell in basket July 2013 when I had a heart attack (left arterial descending). That saw me incapacitated and sedentary for 3 months and 8 months off work until March 2014 before I was fit enough to return. On medical advice at that time I upped my carb intake and resumed glicklazide & metformin. (Big mistake)
Reckon I've hit paydirt with this doc. He was diabetic specialist now come to work in local surgery as a GP.
After my telephone convo Wednesday he called me in for an appointment on Thursday. He suspects I have an ongoing bacterial infection of some kind and had me provide some samples for testing. Also gave me medication, amoxcillin, clarithromycin & lansoprazole - which a good old google search points to helibacter pylori, fairly common, although he urged caution on jumping to conclusions. As I also presented other symptons he is convinced that this and and a couple of steroid doses for asthma could accounts for higher glucose levels and extra glic may cause weight gain (new one on me).
So . . . back to to 20 - 50g carbs per day starting tomorrow. Will need to work meds as we go.
