I'm 50 years old. I hv taken 40 MG paxil for years switched to celexa by Dr. Not feeling well. I hv nausea, dizziness just a flu like feeling. I'm terrified to try the celexa so I've had nothing. Have had alot going on latley... two sisters passed away within 5 months of each other, we moved, just alot. Maybe I'm just phyching myself out..scared always I'm having a heart attack. I hv xanax it helps a bit. My sister's passed of heart related things, had a hubby die years ago of a heart attack. Not sure if I'm sick or its the med switch or lack of taking it. Has anyone quit paxil and started celexa and been ok? Please help I'm so scared! Thank you!
