I don't get it. What you're posting is about forcing weaning when you don't want to, after the fact. Why would you come here to post about it? Why not come here first, to learn coping techniques in regards to parenting a high needs baby? Why not ask how to increase your production? Why not ask how to successfully pump? Why choose to pump when you have a baby that is growing and is healthy?
You said that you got him to sleep longer at night which caused him to nurse more during the day. Completely normal. Why is that a problem? It's to be expected and is totally normal behaviour. Sorry - but your post doesn't ring true. If it doesn't ring true, it probably isn't.
How often are you pumping? If you're not pumping every 1 - 2 hours, just like his pattern for nursing, you aren't going to be able to keep up with his demands. He wanted to nurse that often because he needed to. If you don't match that schedule, you won't be able to bottle feed him breast milk either. Are you supplementing with formula? Not that you asked, but there it is.
Some babies are high needs. Some babies don't like car rides. Some babies nurse more often than others. If you've chosen to wean, why post this first? Why post this in the breast feeding your infant section rather than the weaning sections? I call troll.
