I-Beam Seatpost

I've had a big weekend in afan, yesterday did white's level on the final descent the seat just fell away.
Today did the wall and every 20mins or so i had to stop to tighten it up as the seat was falling off or sliding around, which got really annoying towards the end of the ride.
What can be done? threadlock? or ditch it for a normal post & saddle.
