topcattone, I always said I would not advice anyone to stop their meds as it is dangerous ground. However, knowing what I know now this would be my plan. I would stick with the Metformin while I am in the changeover phase, especially as I will want treats on my trips away but I would start the diet, as Frog say, it will get you used to low carbing ready for the big push.
If you look at what your meds do they are to keep your BG low(ish), if you can do the same with your diet then you don’t need the meds and you could even be taking too much as your BG has gone down anyway. You do not want to go hypo so when you get on the diet proper check your BG regularly and if it is going down, reduce your meds ever so slightly for a few days. The worst thing that can happen is your BG will go up and you can put the dose back up if you want. If your BG continues to go down because you have been sticking to the diet then reduce your meds again. Just take it slow and don’t worry. Not taking your meds will not kill you (I hope) just listen to your own body.
I was looking back on a post from mid July (I started the diet on 21st June) and I was asking a similar question. I said then that being on 38 units of insulin I was going to reduce to 36 and see how it was. I was so scared, what was I doing to myself. Well, read the above, the only risk was for my BG to go back up. I am now on 24 units daily and have also reduced my Glycazide because I was having hypos of around 3.2 in the afternoons and I found out it was that drug that caused them. We are learning here all the time. Stay safe and keep on keeping on…..
