"day 1:  took my first dose of 25mg last night about 2200ish.  i was still wide awake at 0100.  this morning i awoke feeling angry and irritated....reading many of the comments here this seems to be an issue with this medication.  i have had 2 failed  back surgeries and am trying to avoid the fusion every dr has said i need.  the failed surgeries have made me extremely fearful.  i have  never ever in my life experienced anything so painful in my life.  in 2000 a microdiskectomy and laminectomy led complications. a meningocele  the size of a football on my lumbar region.  spinal fluid coming out my nose and ears.  my head was going to explode.  now i am willing to try anything to avoid surgery.  i&#039;ll try this for a few weeks... we will see"
