Birdie, can you post a picture? Toni

When was the last time you watered the plant? It sounds like (without proof by pictue) that it's under watering. Sans tend to curl their leaves when they are dry. It could also be over watering as some plants tend to go through drought symptoms when they have too much water in the soil. We really need a picture.

very narrow leaves means it was not getting enough light when stalks were growing, so even if you give it more light, the base is still very thin and new leaf tends to be narrower and weaker. sansi really likes bright light and even sun, once it got used to be outside. try moving it to a brighter spot. if it's actively growing in warm (above 75F) conditions it likes more water too.

This may help a bit

Here is a link that might be useful: maybe??
