I'm 61; started 2 days ago at 2.5, now 5 mg on third day because of no physical side effects Yet except racing and loud heartbeat. Today, however, I feel even more dead, if that's possible. Tough to concentrate on my work, not sleeping, no interest in doing my workouts (which is Really a huge sign in my case), no interest in eating and food does not taste good, don't want to talk to anyone. It was already like this before, but today is suddenly crazy worse. No other exacerbating factors that I can think of that would complicate things. Ah -- I took 3/4 of a 5 mg valium to try to sleep last night. Hope that provides enough introductory material for a respondent.
