"i am a professional program designer and had a problem with thought activity which made getting sleep a real chore. it became such a problem that my physician recommended my taking lunesta 3mg about a year and a half ago. i have not really noticed the after taste many have reported, but do have some dreams (mostly repetitive type problems that are work related) but, the trade off is a really good nights sleep. i have energy the next day (my own, not enhanced). it will usually deliver 7 to 8 hours and not wake to a drugged feeling. i wish there was a generic which would save me money.
