Thanks so much for all your replies. It is really helpful reading them. I must say my stable is not perfectly 'normal' most of the time, I'm usually a little high, low or mixed, just closer to the baseline. I must add that for around half of the year I am very unwell so it is quite debilitating. I have had ECT three times in the last year. It has been a tough one. The rest of the year I have been moderately unwell or close to baseline. I tend to suddenly switch epidodes at times too. It is happening right now. Deeply depressed and mixed to hypo literally overnight. I'm happy with this change ��
