Hi, My name is ***** ***** I am happy to assist you. You are fine with your medications as there is no requirements about those. As for the water bottle; what you can do is after screening you can purchase water from the airport as that is already prescreened and approved for flights. You can not take more than 3.4 oz of water through the check in process. But anything purchased at the airport is approved for flights. Please let me know if you have further questions.
