What is the lowest dose of Escitalopram that has helped you?

I know this is an old post, but it may help someone, just wanted to add that everyone reacts differently to medications, benefits, dosages, potential risks, side effects... etc..

I was on 2.5mg for the last 18 months of my time on lexapro. It is an extremely low dose but I worked down to that slowly after being on 10mg for a few years. I had to do a lot of self help along the way, therapy, meditation etc and alongside that the 2.5mg worked a treat. Was it placebo at that dose? Possibly!
When I eventually came off I stayed off medication for three years. But life happens and covid plus many more stresses in life has bought me back to medication!
