10/20 mg is a maitanance dose, at least that is what I was told.
So you need it to stay well.
If you are not as active as you used to be and feel you want to get back to that level, try and see an occupational therapist, they can get you reduced price access to a multitude of classes, gyms etc and some will go with you for Moral support, also discuss with gp if there is an alternative, as I say I was on seteraline for a spell. Might be worth looking into xx

I was on citalopram for a lot of years before I was diagnosed properly.
They chopped and changed between seteraline, citalopram and excitalopram
Firstly I would say absolutely don't stop any prescribed medication. You may feel your ok, but that just means they are working.
Even If you come off them gradually, you risk being much worse.
So you need to talk to your doctor and tell him how you feel. Please do this don't just stop.
You didn't say, what dose you are on ?
Depending on the dose you may be allowed to reduce or may need a change of medication.
Only you know how you feel, so tell them, as if you don't it will have an effect on your future treatment as they will not have the full picture. Xx

I would taper off of it. I have gone two days without it on accident and I got so depressed and anxious and very sick

Please do not stop talking ur meds, I did and had a mental breakdown, I've gained a lot of weight due to meds and no matter wot I do I can't get the weight off, I would love to be back to the weight I was but know I need to get my mental health under control and maintain it before I can start decreasing my meds, plz hang in there x

I stopped Citalopram 40 mg abruptly in March of 2017 due to not having refills, I experienced brain zaps, extreme nausea, balance issues, being confused, being fatigued, vomiting, increased panic attacks, and attempted suicide twice. I felt so horrible and on edge all the time and quit eating. It was as if I was sick every day for two months and couldn't hold myself together. And my fiance and I stopped being intimate. I even lost my job and had to be in inpatient care for mental health. Never stop your medication cold turkey like I did. Talk to your doctor about weaning yourself off of it. Finally in May I had gotten my Citalopram back and I've been feeling much better.
