Update - almost at the end of week 15 and had a review with my gynaecologist.
She's very happy with the improvement in the VA, and a uterine scan shows no thickening. No real answer for the headaches/sinus discomfort, but as it's a minor side effect I'm happy to live with it and there have been less the past 2 weeks. As I've restarted the Vagifem it could be the extra Oestrogen keeping them in check.
Libido is still very good compared to pre Tibolone, but does have peaks on and off, and hasn't gone off the scale again as it did in the first month. On refection it's probably safer if that doesn't happen again.
As I've had no increase in facial hair, and overall my reaction has been very good, she thinks it's a bad idea to add in Testosterone gel - in case it knock everything off balance, and putting my sensible head on I have to agree.
Energy levels still good, absolutely no hot flushes, joints are better but I have an odd day where they ache a bit, but not as bad as previously.
Mood very good and positive.
Weight - no increase, actually 4lbs down before Xmas - probably go back on though as full of a cold and not exercising ATM.
So, just going to continue under care of my GP, unless I have any issues. I did ask her how long I could continue on this regime and basically it's up to me, as long as I keep healthy. She actually has one lady in her 80's who refuses to stop HRT, and as there are no contraindications to her continuing she's not arguing with her!
I won't update further unless anything changes, as it's all pretty stable for me now.
Good luck to everyone else trying Tibolone.
