So with the lithium I should probably go with the 300mg 3x's a day then? To see any kind of improvement/difference. What is the therapeutic level for lithium? My last doctor had me on 600mg 2x's a day. I had my blood lvl checked once and he asked if I was taking it as prescribed(and I was) because the levels were very low to non existent...Don't know what that means. My current doctor hasn't had my blood lvls checked yet, but I've been taking it for about 5 weeks or so, not for sure
