Hi FiSH,
Regarding your non-stick wok: It sounds like you have been over enthusiastic with seasoning the wok and have probably put too much burnt oil on the surface.
The seasoning on a well used wok is actually very thin, so much so that you cannot feel it on the surface of the wok. It should feel super smooth to the touch.
The good news is that for cooking curries, which tend to be pretty oily, there is not much of a sticking problem even with a brand new wok. It's a different matter trying to cook a chinese fried rice without using much oil.
If I were you I'd give your wok a good scouring back to the bare metal and let it season itself through normal curry cooking.
Cheers,
Paul.
