It took me 9 weeks to taper off an anti-depressant. If you want to come off then maybe ask if you can be referred to a Psychiastrist or contact MIND charity for advice. If you are OK with where you are now, then continue with your regime. It's all about getting through the day
GPs do offer support, mine certainly helped me by offering me advice, appropriate withdrawal amounts of the drug and I learned to rest on the day after the dosage was lowered. My worry was that the side-effects would never go away and also that the next drug wouldn't help, so my feelings as well as physical were psychological driven by fear of being ill again.
My symptoms were: fear, headaches, queasy tummy, woozy feelings …….. then for 3-5 days I would feel OK until the next low dose ……….. but it did work.
