anxiety
"Crazy, vivid dreams.  Dry mouth and insatiable thirst.  Increased appetite which subsided after a few weeks - stock your fridge with healthy food only or you will stack on the weight.  Can sleep the entire night without waking however oversleeping is a problem (10 hours) and I don't want to get out of bed (the vivid dreams are more exciting than life).  Less anxiety.  Increased concentration, less procrastination.  Sensation in my eyes (dry?) - people say I always look tired.  Restless leg syndrome for first month of treatment.  I'm surprised nobody on this forum has mentioned vivid dreams.  "
