Indeed, and it can be so difficult with all of the conflicting information. I find it important to reassess my own needs from time to time, as I have several medical conditions, and the need for much medication. I do prefer to take as little medication as possible, concerned about polypharmacy as I get older. Though I do believe Metformin to have benefits for some and when I did take it was fortunate not to have the uncomfortable gastric problems some people report. The meds don't always compliment each other, and there can be reactions and side effects. I often find the friendly local phamacist to be more knowledgeable about the meds than the G P.
