Post SRT can be an incredible ride. Sometimes I felt like we were on the down slope of a roller coaster and hanging on for dear life.
There are some things you can consider now that you know you are seeing some downward pressure on the dose. One of the things Melissa mentioned is a "depot drainer". What some people with larger dose cats do is a smaller dose, affectionately called a BCS (big chicken shot), or 1/2 dose, the cycle after a reduction is earned, to try to drain the larger depot. This is the complete opposite in idea to the "shooting through the bounce", but similar in that you return to the new lower dose the cycle afterwards. Some people use a 1/2 dose BCS, I found a 2/3 dose more effective for Neko - though truth be told, I only did it a very small number of times. After first SRT, Neko was guaranteed to bounce to the moon after a reduction, so it wasn't needed.

Second SRT she was more regulated and I had to be cautious. Whenever I got a reduction number that was quite low (20's on the human meter!!

) that was grounds for a BCS for her. Eddie is looking much more regulated and less bouncy so a BCS might be something you want to experiment with to see if it helps. Especially if he earns a reduction during the day, that 1/2 dose might give you more sleep at night.
Other tricks I used, were sometimes back to back reductions. Meaning reductions two days in a row. I also did larger reductions than protocol called for a couple of times. That could be handy if you need a bit of a breather. It's OK if he runs in slightly higher numbers a couple of days if you can't monitor closely due to work or other reasons.
