I have been on 10 mg Lexapro for about a year. It worked great for about 6 months, then seemed to stop. A month later began to work again, then 4 months and it stopped again. What could this mean? I will say I do drink an alcoholic beverage every night, but have never had that be an issue, but winder if that now causes it to fluctuate in it's effects? Also - I take fish oils, tumeric, magnesium, which I know can help with anxiety.
