"new to this generic brand, venlafaxine xr 150mg capsule, pharmacy has new distributer.  easier to swallow capsule,  (it&#039;s only been 2 weeks).   the first time taking it, i opened capsule in food like i&#039;ve always done, but bad reaction!  had to call in sick to work, it was like i was drunk!.  i do not drink alcohol at all.   other problem i&#039;m sleeping all the time at home, very annoying, not getting anything done.  work is fine. is this usual?  hope this helps, i did tell my pharmacist, to help out other customers."
