Hi Superanxius,
I too I'm on lexapro and have found the same thing as you are finding out about it's side affects, alcohol is a big one for me for I have found a craving for it nightly were before I could have a 6 pack last all week. I know this is not the best thing to say but also having CFS I have found that alcohol and pain killers (not together) tend to give me a boost were before I could not work for long at all and if I over did it working I would be down for days at a time and in fact years ago I had knee surgery done and I had a case on, if it wasn't for the pain killers I would not have been able to have framed in my home with in a months time, something again when I put my finger in a saw blade I was back on pain killers I became a workaholic while out hunting for moose we dropped 2 bulls were before my buddy would have to do most of the work for me but I'm getting off track on this but I have talked too others here that do have problems with there sexual performance mainly there lack of drive or being unable to finish.
But I agree you are not alone on this one by far
