I was taking my Spiro once a day as well and it was more beneficial than taking it in a split dosage. However, my doctor doubled my Spiro dosage so I now take it twice a day (again, 12 hours apart). As far as splitting up the dosage multiple times a day (as stated, four times) - I tried that, however, that didn't make me feel right. Not to suggest any wrong doing or incorrect information, as we all know, hormones affect us all differently. For some taking it multiple times a day may work best, for others, twice and for some once. YMMV.
