"in my never ending quest for migraine prevention, my doctor decided to try doxepin to try to take out the migraines, the anxiety, and the insomnia all at once, figuring it &quot;couldn&#039;t hurt.&quot; well. it hurt. no effect on migraines, sleep, or anxiety. none at all. it did, though, drop my blood pressure so low i couldn&#039;t walk for long, needed to lean on walls to stay upright, couldn&#039;t carry a cohesive conversation because i was too foggy to remember what i&#039;d already said - in short, it did no good and left me unable to function at work, safely drive, make it up the steps to my bedroom, etc. pulse also became erratic. and? i was only on half the child&#039;s starting dose. it was bad enough that i stopped it and then told the doctor."
