Anxiety treatment symptoms and conditions

Just discontinued usage of Celexa for anti-anxiety treatment. Dr. is putting me on different meds due to the side effects I experienced. I was on 20mg, and it put my brain in a fog about 5 hours after taking it (not a good place to be for an engineer...). I mean I was just STONED for the next hour, staring into space! I tried to take 10mg, but it couldn't calm me down enough. Taking it at night didn't help either, still felt like I was on the ceiling the next day. Tried to take it every other day, but wound up really paranoid the days I didn't take it. It was like living in a Monty Python sketch where I felt like some giant foot was going to come stomp me into the ground at any minute.

I really need a med that will work quickly and effectively in the morning, and diminishes as the day goes on. Maybe I'll have better luck with something else, this one was too weak in the morning, too strong in the afternoon, withdrawal too terrifying. I didn't experience any other side effects.
