Ft hood symptoms and conditions

I am 39 years old and very active. I have been on Singulair for about 2 years now. I did not think I had any problems while on the medication because it did help my breathing. I am now on an antidepressant (Lexapro)which I began about a year after I began the singulair. My depression however started almost a year before I actually got on the Lexapro. I had alot going on in my life so I just equated my depression to that. However I am realizing now that maybe the singulair triggered my depression. I ran out of singulair two days ago and am experiencing withdrawal symptoms, extreme tiredness, stuffy head, and I had heart palpitations last night, which I have never had. The withdrawal symptoms are why I began researching the medication because I couldn't understand how being off of it for such a short time could cause such an effect. I was on Singulair once before about 6 years ago before I retired from the military while I was at Ft Hood before I deployed to Iraq. By the time I left Iraq I was on multiple medications, Singulair, Claritin, Advair, Emergency Inhaler, When I arrived in Iraq I became ill and listed my medications. They were in shock and took me off everything except Claritin and I was fine. It wasn't until I returned home I began the Singulair again. (Why? I guess I never equated it to causing my other issues until now), I am also taking Zyzal and Lexapro. I see now that every time I take the Singulair it leads to additional medications to other things. I am going to stay off of it and hopefully be able to wean myself off of the Lexapro as a result. Unfortunately I probably will still need to take an allergy medicine. Thanks everyone for posting this useful information. I have two kids 6yrs and 12yrs and I know now that they will never take this medication. They have allergies like me so it is very probable that eventually it would have been mentioned. The allergist/asthma doctor is adamant the 12 year old has asthma but I never gave him the advair that he wanted him to take because I did have side effects from that medication that I did recognize myself and my son is the fastest runner on his select soccer team and extremely athletic without it, no emergency inhaler needed or anything.
