Fluoxetine prozac symptoms and conditions

I am 39 years old and have been on Omeprazole for 6 years. I have had the worst year ever. I was always a healthy and fit guy until 2008. I had chronic headaches and extreme fogginess which led to me having an MRI and seeing a chiro(all negative). I had chronic chest pain which led to EKG's, stress tests, ER visits, and tons of blood work ranging from cardiac, glucose, liver, renal, thyroid, etc...(all negative). Did gastroscopy and found esophagitis and gastritis. Upped the dosage of Omeprazole. Then I started getting tremors, muscle cramping, muscle pain, fatigue, blotchy red skin, and continued fogginess and lightheaded.

Did I mention i still have constant heartburn despite all the Omeprazole. I have done everything...tilt up head of bed, bland diet, no coffee or alcohol, no eating late evening etc....

Doctor put me on Fluoxetine (Prozac) for all my stress and anxiety from these crazy symptoms. After seeing this site and reading all your testimonies I am now thinking it is from the Omeprazole!!! Scary thought to stop since my chest pain and heartburn can be pretty severe and constant. What do I do? Feel like I'm caught between a rock and a hard place here.
