"i have suffered with severe anxiety and panic attacks, which manifested itself into not sleeping.  i literally stopped sleeping for several days.  ended up in the er a couple times and at the doctors all that week and finally had to be admitted to a mental health facility because nothing they were giving me was working.   i literally thought i was going to die.  after 9 days they finally found something that helped me sleep.   it was a combination of doxepin 100mg, xanax, tramadol (which soon switched to benadryl)  and ambien.  these drugs gave me my life back and slowly restored my sleep cycle.  after a year or so i was weaned off the ambien and then the benadryl, so now i just take the xanax &amp; doxepin (now lowered to 50mg).  amazing."
