Asacol HD or Colazal

I will be heading to see my doc in the am and we had spoken in the past if I had a flare again he would have me try colazol. Long story short I had taken asacol hd but between them messing up my prescription I dont feel I gave it a fare chance to work properly. My question is what would any of you say would be best for me at this time. I never had and bad reactions to asacol that I can recall. I am taking 6 a day now and seem fine but its only been 24 hours. I just want to have some opinions before I go in tomorrow because I know I will be put on wither asacol or colazol but most likley per our last convo colazol. I had made the suggestion to my doc before about colazol. I think colazol would be less expensive also. Thanks for the help.

Thanks for the reply.

 He has me on the max dose 3x2 of asacol 800hd untill I get this infection and flare under control..I see him on the 17th and will ask him about other less expensive meds then. I didnt know copay varied for certain drugs.
