Hi mummyp - sent a long reply yesterday but it isn't here. Sorry don't have much time now. The thing is with these meds they react differently with different people I have no experience of SSRIs as am on an old fashioned tryclic. It's difficult to know whether what you are feeling is withdrawal symptoms from the reduction, which in my completely inexperienced eyes seems a big increase.
I would go back to the GP and maybe not thinking in terms of 4-6 months for this or that, but tell him/her what you are feeling. If you go back up to the full dose and you are ok, then you will know it was the reduction causing the problem.
I was on ADs for 14 years and no problems at all and 5 months after stopping them (very gradually) I was having a severe episode of depression.
Hope things settle down again for you. But as for blips, yes yes and yes again, I am still having them a year on from the beginning of my depression. Far more good days but then a row of bad days. It's all very frustrating an exhausting isn't it.
Why are you so concerned about getting off them - if they make you feel better, there is time enough to think about coming off them when you are completely recovered.
Had it not been for the fact that you said you had the feelings starting to come before you went to the GP it would seem extremely likely that it is the reduction in meds causing the trouble. Were you anxious about going to the GP and could this be the reason you were feeling dep/anxious before you went.
There is a poster on her (nickname Natsyloo) who is very experienced in PND - she has suffered herself and has started a group. I'm sure she would help if you put a call out for her
