chronic fatigue syndrome
"I have had a horrible CFIDS relapse that we think occurred to due a CMV infection.  I could barely function at work due to fatigue and brain fog.  The doctor finally agreed to prescribe modafinil 100 mg in am and 100 mg midday.  I feel so much better, but the insurance did not want to cover it.  We battled for a week and finally got approval.  This med has worked wonders for me."
