i didn't want to take medication at all because it was "for life" but the doctor said it didn't have to be, the reason for the for life thing is because when we stop taking them, the good work they were doing will be undone, so in my opinion only and I'm not advising you or anyone to stop taking anything if for example you were taking a certain medication (for example statins) for high cholesterol and your cholesterol went down to a nice level you may for example be able to reduce the statin whilst keeping an eye on your chol level to see if it went back up, i use statins as an example because i have personally knocked them on the head for several reasons, but will monitor things so i know if i need to take them again, the docs seem to be keen on us taking preventative meds for just in case, this is nuts to me otherwise why don't we take paracetamol in case we get a headache, or have chemotherapy in case we have a cancerous growth we don't know about, i have stopped or reduced meds when i decided it was the right time and not under medical supervision because i have very little faith in my doctors but do keep an eye on test results to make sure I'm not harming myself, you also have to consider other benefits to medications other than the reason for taking them, metformin is a good example because apparently this has other benefits other than bg control, i am in no way medical, everything here is just my uneducated opinion
