"have had sleep problems last 10 years or so. went to sleep clinic, apparently i do not fall into deep sleep stage. doctor put me on ambien 5mg. wonderful. i slept all night and felt great next day! fast forward 4 months. end up being tested for lupus, lyme disease and bloodwork galore because of muscle and joint pain that would show up  in different places and i was suffering extreme tiredness and weakness during day. all tests negative so doctor wanted me to stop taking ambien and switched me to trazadone. been a week now. so far so good but insomnia is back. will not be continuing trazadone. causing excessive pvc&#039;s and feels like my heart is going to burst out of my chest. does not help me sleep even a little. sad about the ambien."
