Thanks everyone for your replies.
Meadowblue, I am only taking the omeprazole plus starflower oil which I've only been taking for the last month. If things don't settle down soon, I might take your advice and at least ditch the starflower.
Bev, sorry to hear you're struggling like me. I'm thinking of asking doctor to refer me to a gynaecologist, perhaps you might do the same. I understand that many GPs jump to 'mental health issues' as they don't understand the hormonal link. Don't know if we can believe this, but the article said these issues last 5 years. If that's true, maybe I only have one year left.
I truly believe that HRT would make all the difference to me, but I'm really worried about the breast cancer link as well as unwelcome weight gain.
