4 months ago, after being on Citalopram for years, I had a blood test as I was feeling so tired and achy. turns out I had a big vit d deficiency. I should have worked this out myself as I have noticed over the years I need less Citalopram in the summer than the winter! I have since been on large dose of vit D as prescribed and feel so well I cannot describe. I have also added in vit c and zinc, omega 3, magnesium, vit b and vit E with good effect. So much so I have gradually reduced my citalopram from 20 to 10 mgs over the last 6 weeks. I will stay on 10 mgs for about a month before I decide if I want to reduce further ... So scared of a relapse even tho I really know I am ready... just want to make sure my body gets used to being citalopram reduced without shocking it! A massive success.
