My doctor has prescribed BuSpar (buspirone) for my anxiety. I'm supposed to take 5mg twice a day and after a week I'm supposed to take 10mg twice a day, until I meet up with her again in a few weeks. It started working on the 3rd day and I felt a lot better about my anxious thoughts. However, today is the 6th day I've been taking it and I feel that some of the anxiety has been back. Yesterday I was late about a couple of hours and I could really feel the anxiety coming back. I took it immediately after I got home and this morning. However, I started feeling anxious again a few hours ago.

I'm confused on what is going on. Did being out of it for a couple of hours could really bring back all the anxiety I had or is that part of the "2 week plan" of the body getting used to the medication?
