Hello, To reduce the side effects of Paxil, you can take acetaminophen for relieve from discomfort that you are experiencing. Take water, soups or juice to stay well hydrated. Take ORS, to help support your body electrolyte system. Dehydration and imbalance in the sodium-potassium balance may cause you such symptoms. Maintain your blood glucose level and blood pressure. Stay well fed, take home made nutritious food. Avoid stress of any kind (physical or emotional). Since you have history of generalized anxiety, you are suggested to get connected to a counselor. GAD treatment is done with medicines (SSRI s) but is best when the treatment is combined with psychotherapy. Anxiety disorders are treatable, it may take some time though. Physical exercises, stress management and relaxation technique s are helpful. You may need the help of cognitive behavioral therapy, to a physical therapist. Maintain healthy weight, cut on addictions if any. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
