6MP takes, at minimum, 6-weeks to work. More realistically 3-months, as they start you at a low dose wait a while, and then up the dose (which takes another 6-weeks to have an affect) .
It was a placebo-effect if you felt anything before 6-weeks.
Could it just be that it took the increased lialda and budesonide 3 months to fully work? I went up one pill of lialda and added budesonide mid September.
