Hi..it's possible and has probably happened to many of us.
How long were you on the 6 daily? I think you should have stayed on them...or just added one pill per day to get up to the 6 daily (3000mg)
I would suggest you stay at the pred level now, don't up it and discuss the rectal meds..have we not suggested it to you? They're available in the philippines, right? If so, your doc should have suggested them to you.
You could ask him about Salofalk retention enemas (since I see you used the pills in the past).
