He started 20 mg. daily a couple of weeks ago, and the difference is amazing. Granted, he is still needing 11-12 hours of sleep at night, but his brain fog is so much less now. And he's going to school (college)! He loves his computer class, and drove off to study for 4 hours yesterday and enjoyed it.....he's actually excited about school! I haven't seen him this good since he came down with CFIDS 14 months ago! Thanks for your prayers everyone!
