I am on day two of a round of cipro and started my period so took midol yesterday. I took the midol about an hour after the cipro, and immediately became nauseous and threw up. I was fine after that, spaced things out in the evening and only took 1 pill of the midol. While I wasn t nauseous I became very jittery and only slept 1 hour last night. I woke up with very tight muscles, with occasional random clenching of muscles and tremors. I will not take the midol again but should I contact my doctor about switch antibotics? I am very sensitive to side effects in general and I am worried it is causing anxiety and sleeplessness . I feel quite wired. Thanks,
