I too would suggest going to a Dr. for a complete physical and to talk about how you are feeling. Many alcoholics/addicts self medicate underlying problems and once they're clean the underlying problems become clearer/worse. I know that once I initially stopped drinking and had been sober about 2 months my depression got worse than it ever had, and I wound up being hospitalized for 8 weeks while they got my meds sorted out.

Good luck.
