Venlafaxine has been a nightmare for me. My Dr titrated me incorrectly and I crashed and burned...every severe side effect you can think of (3 months flat on my back), had to leave my job (retired which I am ok with that). I was on it for approx. 18-20 years. When I was going thru horrendous withdrawal they wanted me to go back on it but I was too afraid so only accepted a small dose of it along with a cross dose of fluoxetine (supposed to be easier to go off of). Though I went thru the worst (vomiting, vertigo, migraines, burning stomach, tremors, insomnia, lethargy, etc.) I am now left with idiopathic neuropathy (painful on a daily basis) - was Venlafaxine the cause??? I still don't feel right overall. I have now titrated and went off Venlafaxine several weeks ago -- managing it fine. But in general my body has never recovered (I was well and healthy before AWS). My diet has also been radically changed. I was vegetarian but am now low/no sugar, GF, no nuts, rare dairy, no onions, nightshade plants, mushrooms...etc....low to no processed foods to clear up inflammation per Neuropathy treatments I sought at Loma Linda University. But I still feel systemically off like the fluid in my blood needs to be cleaned and filter out (don't know how else to describe it). It's ironic as many of my tests come out in normal ranges... making it hard to pinpoint a cause. It hasn't yet been 3 years so perhaps there is hope for a normal body again. I too have experienced sweats but seem to be less as of late.
