I was prescribed metronidazole and ciprofloxacin four days ago for diverticulitis. Because I have been on so many antibiotics since August ( kidney stones, colonitis, sinus infections ) I decided I would only take the metronidazole. Last night, however, my stomach began hurting again and I could not sleep. At 4:30 in the morning I decided I would start the Ciprofloxacin again. I had taken it for ten days a a few weeks ago for severe stomch pain. Today I feel terrible: dizzy, nauseous, lethargic, depressed, no appetite, tremors . Is it possible for me to go off one or both of these drugs? Are there other drugs I could take. I have read that I must continue with the meds or I will suffer a relapse. What will happen if I stop taking the drugs? How long will I feel this terrible? What can I take, if I must continue, for dizziness? Thanks
