Don't know if you get Modulen there, but we were allowed to mix it with Crusha (milkshake flavours), so you could change the taste whenever you wanted, there was strawberry, chocolate and raspberry just off the top of my head.
I tasted my son's Peptamen 1.5 vanilla drink today. It was like an instant breakfast, with a gross, chalky undertone. I don't know how he managed to drink 8 of them every day.
