"i am taking ssri to help me deal w my job, and daily life stressors.  i switched from zoloft to buspar approximately 3 weeks ago, due to side effects.  i have sleep issues due to being a night shift person, and probably anxiety, so i&#039;m on ambien as well.  lately, i&#039;m having worse sleep problems, and having weird dreams.  i&#039;ve read, buspar can cause insomnia.  planning on taking my dose all at once during my waking hours.  anyone taking it just once a day?  and what&#039;s your experience.  thank you."
