Hi Sue. I think we joined this forum on the same day. I remember your posts mirroring mine. Know that you are not alone. I too am on proprananol (40mg once a day)...not sure if it has an effect or not but happy to take it. Over the last 6 weeks I have had terrible days of feeling terrified over my foggy memory, teafullness, anxiety and the inability to string a cohenert sentence together. My worse time has been the week after my period (Days 10-18ish). I got to the stage I didn't want to even go shopping or meet with friends. Certain things have helped (a little)....keeping calm, exercise, better diet(soya milk, banana, pruce, honey smoothies), cutting sugar and carbs. A glass of wine can lift it a little in the short term but I pay for it with bad sleep and foggyness the next day. However I must say today things has shifted and I have more clarity and less anxiety. During that week NOTHING I was doing really made any difference to my overall mood, my brain was in overdrive. I have a GP appointment next week and am going to ask about ADs and blood tests to try and find which hormones are doing what in the bad week; maybe ones you can just take when you feel particularly low. (Just an aside I was put on Ellestre Duet back in April for insomnia and had horrid side effects; nightmares, headaches, paranoia. GP told me to come off it straight away when I phoned her. A shame as it has put me off HRT completely although I know there are different types. So don't be scared to check in with your GP with a phone call if you want advice en-route or you get sudden new or worsening symptoms.
