"i developed anxiety attacks, as many do after a total thyroidectomy.  i suffered for a year with inadequate thyroid treatment and all the awful things that come with it. then developed panic/anxiety attacks.  they would last 6 or 7 hours at a time.  i would barely feel better and then i got another. ativan helped in 15 minutes. i&#039;ve been taking it for two months and it has given me back the small part left of my post-thyroid life. thanks to my thyroidectomy, i will never be well again.  but at least i don&#039;t have panic attacks."
