Thanks, everyone. At the moment, it's all feeling terribly random, sooooooo many variables! Is the site/dose/delivery method the issue? Who knows. So, yes, I'll give it the ten days and see what the bloods are showing. I think, if an absorption issue proves to be the case, it may be that a higher dosage by the simplest delivery method to manage, is what's needed rather than flitting from this to that delivery method at minimum dosage. I'll keep you all posted. Thanks again.
