anyone had problems with Luvox CR

helo  I am male 31yoa,  I just went to a Doctor about having possible anxiety and or panic attacks.  My job is very stressful and I seem to be worse during the week while at work but it sometimes happens on weekends too.  I have been getting lightheaded for approximately 3 years now and all the medical test have came back normal.(????)  So my doctor sent me to theri. and to talk with a phy.  He gave me Luvox 150mg on Monday.  I  took the one pill that night and starting late yesterday had sever hot flahes on the torso area of body and pressure in head, VERY LIGHTHEADED and sick feeling.   I DID NOT take another pill last night due to this.  HAS ANYONE EVER HAD A PROBLEM LIKE THIS WITH THIS MEDICINE??   I also have very weird and scary dreams last night.   Just trying to figure all this mess out.   Thanks for any help
