Welcome, thisiscrazin! When I was too short to pineapple, I used a satin pillowcase to sleep on. Actually, I still use the satin pillowcase even with my pineapple. The satin reduces friction so there's less crazy bed head in the morning. Sometimes I would use a satin sleep cap. Both methods were helpful.
I can't speak to your water only method. But I can tell you that many curlies wet their hair daily with good results.
