Zyprexa and fear

my son started zyprexa almost 3 years ago and has gained over 100 pounds! my little boy is gone, hes double the child he was, and most of it was in the first year. He stopped taking zyprxa 3months ago, the first thing we noticed was how good his face looks, now his belly is even with his chest, his self confudence is better than I've seen in him in years! He doing better in school than he has in 3 yrs. Hes getting out of the house and going on with life. All this in 3months, makes me wonder about if he really needs the lithium & wellbutin, not ready to stop any other meds. yet, but this wonderful change since quitting zyprexa makes me start to think if the pills are just a scam,and the threats of what will happen if you quit is a contrlling fear, if it was my health I would quit in a minute, but its my son,and I'm afraid of taking that chance with him.

I started taking Zyprexa on Friday..today is Monday...I feel less anxiety fear and hopelessness (have bipolar by the way!) but I crave food in the evening...I fear gaining weight I used to be 185...now 150 and feel good about my weight...I also take Epival or valproic acid. My mood is generally down down down,,just want to be happy that is all..want to have positive outlook on life..lyle
