Singulair and strange thoughts

In March I started having a lot of facial pain. Thought my allergies were getting worse. I went to an ENT specialist, had the whole workup (which they cannot still figure out my pain). Anyway, wanted me to start on Singular. I took 1 pill before I went to bed this last weekend. I started feeling dizzy and having violent thoughts. Also I had a lot of trouble sleeping. I still felt "weird" the next day. At first I thought this was a fluke, now I am pretty sure it was the Singular. I don't want to chance taking it again. I am a very heavy sleeper and do not have any problems falling asleep. The anxious feeling and strange thoughts were scary. I am not going to take this medication again. I am going to file a report with the FDA for the side effects I experienced. I am convinced they would have gotten much worse like the other people have expressed if I had continued taking it.
