I have been feeling tired in these days. Maybe I have almost used up my energy to fight with the allergy. And it has been almost a month since I started to cut down my diet for losing my weight. Maybe eating less made me feel tired. I reall don t know. Today the pharmacist also told me that taking Singulair might cause suicide. Oh my god! That s what I was taking! But I have already stopped for one or two days. Singulair is basically for Asthma and Allergic Rhinitis. I have heard and it has been known that Tamiflu, a flu remedy, causes people having suicide in Japan. But this is my first time to hear that Singulair has the same side effect. As I mentioned before that I woke up in the early morning because of the allergy and coughing, Singulair made me sleep much better when I took it at bedtime. Now I have to reconsider before taking it again.
