Keep to a schedule with this one man, one a week, one a fortnight, but keep to a schedule. Also I would do Anesthetize by itself, and the remaining three songs in a single reaction, before you move onto the companion album 'Nil Recurring'.
This is a brilliant PT album but then most of them are. Looking forward to seeing you check out the rest of it. After that can I suggest that you wind back to the Album ‘Lightbulb Sun’ or as someone else suggested check out the latest album ‘Closure/continuation’ which confirms that they still have the magic. Also you really should treat yourself to some Steven Wilson solo work. The album ‘Hand cannot erase’ might just be the best thing that he has ever produced and would be in my top 5 albums of all time by anyone.
Gavin Harrison also drums in Pineapple Tree. Great band. I think you will like Ayreon too. Start with The day that the world brakes down. Then look at both live concerts: Ayreon Universe live The electric castle live and other tales. Then the albums. You will hear a lot of well know rock and metal musicians.
