Singulair and human body

I was first given Singulair at the age of 21. At which time, I quit a job in which I have yet (at 28) to match its income. My doctor continued to give me samples as I could not afford the medication. During this time, I was very depressed, contemplated suicide often and was given a serious of antidepressants-non of which helped. For one reason or another, I stopped taking everything. At which time, it seemed I had a new lease on life. I went back to college, finished my degree, and got a job in decorating. My asthma began acting up again, and again I took singulair and again had to be given antidepressants. I wound up quiting that job too and worked a serious of low paying jobs. Again, I quit, and again found the urge to "live" again. I never connected the two, until this past week. I was given singulair again by another doctor on Wednesday. Thursday I had nightmares, Friday I spent the day crying, Saturday night I began to think of leaving my husband (I also did that ALL the other times I took the drug and we've been together 14 years-I love him). Today is Sunday, I normally go to bed around 12 or 1 a.m., but I am making myself stay awake and have all day. This drug has ruined a large part of my life, please, if anyone notices even a little depression with this drug, Stop!!!! It is not in your head, it is this drug!!!!

Clinical trial of montelukast in the Netherlands.

I noticed two things:

1. The researcher states that sides effects are 10%.
2. The researcher will not allow patients to also take drugs which are metabolized by CYP2C8 because montelukast inhibits that as proved by in vitro (test tube) studies. American studies in vitro said yes montelukast is an inhibitor but in vivo (in people) that it didn't happen. I was always confused by that and would still like to know more

What needs to be explored now is the path of least resistance,the human body is an amazing thing,when things don't work right it tries to fix itself by taking the path of least resistance ,causing symptoms that we will go seek help for,My older son had hydrocephalus at the age of 2,and a shunt was put in, making him shunt dependent, as it would always be the path of least resistance,my dad had a silent heart attack, new capillaries showed up keeping his heart alive ,making this the path of least resistance,some of the behaviors that remain from singulair side effects may very well be symptoms that are taking the path of least resistance, can this ever be reversed???????????????
