I've been prescribed Mirtazepine after a breakdown as Citalopram no longer seemed to be effective. My doctor first switched me to escitalopram 20mg but that also proved ineffective. I'm currently weaning off the escitalopram (am now down to 5mg every 2 days, which has taken me 6 weeks) as I was cross-tapering to Mirtazepine. I started off on 15mg then after 10 days went up to 30mg which I've been on now for almost 4 weeks. I have noticed I feel calmer (am also taking Propranalol) and am sleeping and eating ok and have now managed to go back to work, but I feel very numb, almost like I'm an outsider looking in, and also feel irritable and have no libido whatsoever, I also feel that there's very little point to things at the moment. How long should it be before I should approach my doctor about this/feel more like myself? I saw him a week ago and he said to persevere as it takes time and see him in a month. Advice appreciated!
