I've been suffering from bad anxiety and panic attacks for years. Had all the heart tests including a cardiac cath-everything normal. I decided i can't live like this anymore, so I started seeing a therapist. I was also given a prescription for Zoloft and xanax. I have been putting off taking the meds because of the fear of the side affects. Meanwhile the anxiety showed more symptoms/sensations like dizziness, eyes can't focus, blood pressure goes up, feel like I'm gonna faint but I never do. I decided to start the Zoloft. Today will be day 3 at bedtime. Since I started taking it, I've started experiencing palipitations. I know it will take a couple weeks before it starts working. Will the dizziness and palipitations go away? Would xanax help? Please help.
