^ yea, and sometimes, the leaves won't perk back up, but it will grow new leaves, & those old, wrinkly ones will die off at some point. **Just don't think you need to water it until they perk up... Remember, sometimes they don't. You want to water the roots - not the media, or to plump wrinkly leaves. This would lead to overwatering, and you don't want to overwater, as that would cause the roots to rot.
