It might not be your luck at all, I think its prolly just the thickness of the stems. Mine are alot thinner ,and just popped back to life, so maybe they just need more time. I noticed too, as was mentioned, that temp. has alot to do with it. Mine were in the 'big plants' room andf did not like it at all, too warm, but when i seperatd them to their own cooler space. Bang, thats' what they needed.
I hope it works out, if you are like me i get sorta attatched to my plants and it really bums me out when they are'nt doing well.
