Hi, I don t know where to even begin. okay, I have a underactive thyroid and I take levothyroxine 125 micr a ograms a day. I also am prescribed lasics 40mg a day b cuz I have high blood pressure sometimes, anyways , here is the deal, I don t ever drink any water b cuz I don t like it, I only drink iced tea, well now that I am thinking about it the symptoms that I am having has progressed over time. I started having leg cramps then I would get cramps in my feet, toes hands and fingers, then stomach cramps and then I couldn t go to the batroom, I was constipated and these things progressed over time ANYS, I THINK I AM DEHYDRATED AND MY POTASSIUM AND THINGS ARE LOW IN MY BODY. I STARTED DRINKING AS MUCH WATER AS I CAN A DAY AND I BOUGHT POTASSIUM SUPPLEMENT90MG AND STARTED TAKING THAT PLUS A MUTIPLE VITAMIN AND B-12 SUBLINGUAL AND MY LEG CRAMPS ARE STARTING TO GO AWAY NOW, MY QUESTION TO U IS, SHOULD I BE DOING ANYTHING ELSE AND OR TAKING ANY OTHER VITAMIN??????
