i was prescribed xanax from my PCP. the day my dad died i had anxiety as i was sleeping and thought nothing of it due to the circumstances. then over a year later I would wake up randomly in the middle of the night, like once every few months, w/anxiety.
so when i went to my PCP, whom was also friends of my father, for something unrelated, i mentioned this to him. i explained the symptoms and when i would get it and how i could control it better now that i know what is going on, but he prescribed me xanax to take just in case i wake in the middle of the night and need to help calm me down.
well i've used it probably 10 times maybe since prescribed to me and noticed it helped a bit. i get anxiety while flying too and took it before flying and it helped a lot there as well.
can't say i've ever seen a side effect of it either.
