Hello Yogini my night flushes took three weeks to go on the HRT, but like you I have developed dry mouth (and a burning tongue). Currently drip feeding the tablets to see if it lessens and have been advised to see the course through. However, if your tongue has swollen, think it is best to go back to the Dr (easier said than done sometimes, I know) . Also had a breakthrough bleed that I wasn't expecting, but that is normal apparently. It does seem for some of us that we don't hit the magic cure first off. Are you able to take iron tablets in the interim whilst waiting for colonoscopy, or is that not an option? At my worst with anaemia, I was unable to walk up our stairs, but iron tablets corrected that. Good luck Yogini, keep in touch.
