Asthma condition symptoms and conditions

My son is 17years old and has been taking sigular for 5 years due to allergies and a minor asthma condition, I am also seeing many of the side effects. The major ones are explosive anger, easy frustrations, laziness/lack of motivation, leg pains and cramps in legs, and when he sleeps it is almost impossible to wake him up in the AM. He mumbles and says OK I will get up , then after 15-30 mins and he is still in bed and constant attention by me to wake him, he finally wakes up and says, why has no one tried to help get me up and he is very anger. He has raised in bed, screaming, and punched at me during these 15-30mins, to later say, NO way I didn't do that, I don't remember. He seems to be in a trance!. I have been struggling to figure this out for 2 years now,

I do agree that I saw an easy going kid turn into one filled with anger and frustrations for no real reasons.

Took Advair for 2 weeks for a mild allergy induced asthma condition which I developed after a long bout with bronchitis. My breathing was slightly more comfortable but every day my throat was becoming increasingly sore and my voice was very hoarse. One evening my throat was so sore that I didn't take the dose. The doctor gave me a lower dose which I took for a week but I stopped it after I couldn't tolerate the sore throat( I rinsed my mouth like it instructed). Anyway, since my breathing was better he recommended that I stop the Advair. Well it's been 3 months now and I am suffering from intra costal nerve vibrations, muscular weakness,palpitationsand feelings of malaise. The muscle tremors are most noticeable when I lie down.I feel very down most of the time for no apparent reason. I have even had a holter monitor test for the palpitations but the test was negative. Trying to get myself back to normal with vitamins,diet, exercize etc. Can't believe that it is taking so long for the residuals of the drug to leave my system.
