My Psychiatrist prescribed me this medication for my OCD and anxiety. He said it works right away. I have been on this medication for three weeks. I started at 100 MG 3 times a day. Now I am at 600 MG 3 times a day. My doctor is trying to find the right dosage for me. He told me I should know right away. But I am wondering and want to get some suggestions on if I would know right away? Or would I give it some time?

Thank you all in advance for your kind answers.
