With diabetes discussion/support forums, we all visit and register to ask for or offer advice, share experiences or just come on board for a general banter, and most diabetes forums serve this purpose. As I am a member of 3 such forums, I prefer to stay neutral here, as any forum that is there for the benefit of people living with diabetes can't be a bad thing, and as such should be respected by all living with this life-long condition.
As with all things in life, one must come to such places with a open-mind, and take away what you believe is beneficial to your own ends, bearing in mind that some information provided may only be based on a individuals experience, therefore it may not be necessarily suitable for oneself, so my advice is always check with a HCP before implementing any changes to your diet or medication. My only bad experience to-date is that I was once a member on a low-carb diabetes forum and the advice I received was very dangerous, and had I not researched and asked for a professional opinion on the advice I was given, I may have been causing myself long-term and irreversible damage, so thankfully I kept a open mind and followed this through.
