Are you taking the time released one? I am taking the 90 Milligram extended release tabs. Just started using Duac tonight with this.... Have been on Tazorac and Duac before with AMAZING results... For over two yrs when I used the Taz as maintainence using it everynight, my skin was FLAWLESS... Will be starting that again too, but I really HATE the initial period when your face breaks out... Love the results, just a little impatient with the waiting...
