Suggest Remedy For Side Effects Of Pravastatin

Just now realized that pravastatin sodium may be the cause of me feeling sick. I also have severe nausea, stomach pain with some cramping, weakness, constipation, increased depression, anxiety, hopelessness. I had my gallbladder removed 3 weeks ago. My surgeon told me everything looks good and tests from biopsy are negativefor any infection. He recommended i see my GI again regarding my continued nausea and constipation. I see him next week. My primary dr changed me from taking vytorin bc it interacts with my blood pressure med., verapamil. Started taking a low dosage of pravastatin sodium about 6 months ago. Dr. Increased the dosage to 40mg. Started taking it after my surgery and i have increased nausea, and the symptoms listed above. Can i just stop taking it, or gradually?
