I would think yes since it is a medication made to treat people that have bipolar disorder. didn't the recruter tell you that you can't be on any medications or anything like that? I know this because I was going to join and I'm on antidepressants and a friends of mine had to go off his ritalin in order to join too. I personally thinks its stupid to make someone have to go off medications they were prescribed by a doctor just because they want you to be perfect and crazy enough to shoot to kill if they send you into war.
As a former recruiter, you will be automatically disqualified if you tell them that you are bipolar. Also, you have to be off all meds (except birth control) for 2 years.
