Hi Dorymai,
I was prescribed Clonidine last year on my first trip to the GP, I took them for a while & they did seem to work at first. Like you I had a really dry mouth (& dry eyes, which was a nuisance as I wear contact lenses!). I also have low blood pressure so had to be aware not to stand up too quickly etc, all this said I found that after a few weeks they did not seem to be working so well & I was then prescribed hrt. Hurdity is right, the guidelines are altered now & it may be worthwhile asking about hrt if you are able to take it? I was really against taking it but quality of life as well as the obvious benefits of replacing what we're lacking far outweigh the minimal risks in my humble opinion.
Love Spadger x
