Hi Nina Does your type 2 friend know the risks to her health? If my diabetic nurse had been my only source of information I do not think I would know anything more than recovery times are a lot longer and I must wash my feet before I go to see her (wearing crocs on the allotment is not conducive to socially acceptable trotters) . The Desmond course covered it but if your friend missed that or her group did not make an issue of them the risks could have been lost in the general morass of info.
I find the big problem is finding somewhere to eat anything but cake, burgers, pizza and noodles (I live in Coventry lets just say noodles are a local phenomena). The only places I have found so far are wetherspoons and a local vegetarian cafe. We were in central London a couple of weeks ago and ended up doing Wetherspoons for all 3 meals. We did try to find somewhere else but did not have time to get to the museums.
