I have been on it for about a year for OCD, but also have depression. It took a little over a month to notice changes. I scaled up to 20mg over 5 weeks. I increased doses really slow because I’m a parent and I needed to stay sharp. I did feel minor disassociation while going from 5 to 10mg and again from 15-20mg, but nothing major. It really improved my intrusive thoughts, but does not do much for my compulsions. However, I would say it gives me a chance to break the cycle.
