I've been on the above for 18 months but since Christmas my symptoms have slowly increased. I was at the end of my tether this morning with waking continuously and night sweats. I'm literally exhausted. I called my GP and she said I could double up on patches. It's off-licence but she said within dosage guidelines. If after a month there's no improvement they will do a blood test to see if I am absorbing the oestrogen. Has anyone else had this happen to them?
