This sounds like such a cop-out, but I was actually genuinely concerned about there might be something other than excessive quantities of good red wine and large food portions, that might have contributed to my putting on 2 stone in the space of a single year!
So I took myself off to my lovely GP last week and she ran blood tests for just about everything! I had both my liver and kidney functions looked at, as well as the (obvious) thyroid activity levels...
well, I spoke to her today and my tests have come back fine.
So I'm in a bit of a paradox now, as while this is obviously exactly what I should want to hear, I suppose it does mean that I really do actually have to take full responsibility for the fact that I have done this to myself, and cannot attribute it to influences beyond my control, grr
ahh well, of course I'm happy that I don't have an underactive thyroid which would require medical treatment for life, or indeed anything more sinister, but now I have nothing and nobody to blame, except for myself!!
