Ok, so say you decided, all by yourself, to drop the Met for a month. Would it kill you? Would it even injure you in any noticeable way? Probably not. I'm presuming you have a meter, have strips and know how to use it and that you understand what is meant by a low carb diet and have the facilities and family support to carry it out. Keep a detailed diary, recording what you eat, symptoms, side effects and your blood sugars on waking and before and after every meal. If you need advice on any of these issues, please ask.
After only a few days, you should be able to begin to assess if you are being successful. You can always abandon the trial at any moment if things aren't looking good. If things work, you can carry on for a bit longer, then go and tell (or write to) your GP explaining your success and that you have given up the drugs. After three months, ask for an HbA1c. This will show you if more drugs/work is necessary.
Just a suggestion, it's your body.
