Thank-you everyone for your advice ....you have given me some things to consider.
Michelle .... I am already extremely sensitive to sun. Typical 'english rose' colouring with a tendency to go red as soon as the sun looks at me. I tan in wind so am often browner in the cooler months than when the sun is out.
I was told I might have problems balancing my bloodsugar levels until my body adjusted to the new medications and that has proved the case today. Back to the regular finger pricking (which I hate).
Thanks again everybody, for being concerned enough to post ....this is what I love about Mudcat.
