Are these residual symptoms? Has it been a while you are abstinent? If so I know that certain foods affect me (milk, stimulants like coffee and tea, alcohol, possibly gluten). If you have the chance you can try celexa, an SSRI. It helps me get back to my senses when I get severely lost in my thoughts and depressed. Also I've recently started using Mood Support from NOW foods (5-HTP, St-John's Wort, B-Complex, Taurine, GABA among others)
