I normally take one Singulair a day. Great stuff, really helps. However one time I took two by mistake. Yep, you will see colors and have the most interesting dreams.
Possible new tag ling: excuse me while I regain control over my agitation, aggression, anxiety, dream abnormalities and hallucinations, depression, insomnia, irritability, restlessness, suicidal ideation and behavior, and tremor.
Sounds fun, gotta try that one weekend when I’m not busy! Just kidding...I got off Singulair about two years ago and just use Advair now. Good stuff, I swim, bike, workout, etc.
