Nadine - what is your goal with Tibbs? Are you looking for regulation or do you want to try for remission? In either case, it's much better on his system if he spends more time under renal threshold (around low yellows). Tibbs still has a way to go before he gets there. If you are looking for remission, then the goal is the majority of time between 50 and 120. Other than a possible faulty strip the other day, he's hardly seen any green.
I would try 2.0U again. Tibbs is bouncy and 2.0U will get him bouncing worse for the short term. Until his little body spends more time in good numbers, his liver is going to go 911 and send him bouncing. Neko is also very bouncy. I started seeing a lot of black when we started getting into good numbers, but over time the black went away, then the red, .... pink is still a work in progress. :lol: You have to try to ignore the bounce numbers and focus on the nadirs, or how low a dose is getting Tibbs. Those are the important numbers.
