Awake time symptoms and conditions

I am 40 years old and recently went to my medical facility as I have had a "viral" ear infection for almost a year now, and it is concerning me. I do not take medication typically. My new primary care provider recommended I try Singulair. So far I have taken three doses over three nights. The first night was horrifying, the dreams I had were so scary, and they were tied into reality which was even stranger as the drug also makes you wake up often, then when you fall back asleep your awake time ties into your dreams. I woke up in a numb state. Since then, I also have been extremely agitated, dizzy, mouth sores, acne, fuzzy thinking, light headed and severe fatigue and body aches. Thank goodness I checked out this webpage, as I too will stop taking this drug. I find it very disappointing, how are we suppose to be able to trust our medical professionals to help us with one of our most prized possessions, our bodies, when we are given something to clear up an ear infection only to have it affect numerous other aspects of our lives to such a serious degree with no mention from our medical professionals. This is ridiculous. I guess I'll live with the viral ear infection.......
