Singulair and moody person

I am a 36 year old white male - generally good health. Could use to lose a few pounds but not overweight. I've been taking Singulair for a little over a year and since then (I also take Zyrtec - over the counter and Nasonex) all are for allergies. I since developed acid reflux - went to my pharmacist and she said that most people with this mix of allergy drugs form acid reflux. Anyhow, I am generally a moody person-have always been - too intense and most of the time I am not a go with the flow person-since I've been taking Singulair my mood swings amplified horrifically - I blow up at my wife over stupid assanine stuff - after reading these posts..today is the last time I am going to take Singulair. Wish me luck. I hope the mood swings decrease.

I have been on this drug for approx 2.5 yrs. I am now a moody person with no interest in anything. I try and be positive, but have a headache all day everyday !!!!! on both sides of my head down to my jaw. I also grind my teath badly.I cannot sleep at all, and when I do, when I wake up feeling that I have done a days work. I have had an iritable stomach also. Please if you think that these problems are caused by singulair please mail me .
