My GP initially put me on 1 mg Elleste after surgery which I didn't feel was enough. My oncology nurse and consultant advised I would need a high dose due to my age (38) and I asked my GP to increase the dose to 2 mg. I changed doctors to a more experienced female doctor too and she was happy to increase it and said everyone is different in the dosage required to feel 'normal'. I must say I feel better for it - my energy is increased and I don't feel many menopause effects.
However, my fuse is shorter and I still lack some of the energy I had before diagnosis though and I feel that is probably partly caused by the stress of diagnosis and treatment. It is slowly getting better (stress at work hasn't helped) and over time I am hopeful that will naturally improve as a I recover emotionally. Remember, it's not just the physical side we have to recover from but the emotional side too and that takes longer to heal but we will get there :o)
Good luck with the GP.
