Sorry, gransnetters, I haven't been logged in for a while and didn't realise there were new posts. Thank you for your thoughts.
I took the 60mg for 10 days and then had a small set back. Contacted the online service of GPs re medication query and received a same day telephone appointment. I was taken off the 60mg and prescribed the 30mg which I start tomorrow. Hopefully that dose will work for me.
It was only when I was off the tablets for those few days, pending the new prescription, that I realised the effects on me. Sore back and felt I had strained a stomach muscle. Quite weepy for no reasons - so unlike me. Feeling of sluggishness and slight pain in right temple. I never get headaches now I've stopped teaching. I had thought I was tolerating the dose quite well but obviously not. I put it all down to initial settling of medication into my system. I will try new dose and hope it has fewer effects. I'll post another update after my first blood test (3 months).
