The up and down thing is actually common in stasis. This is one of the very frustrating aspects of stasis recovery. It can feel like 2 steps forward and 3 steps back then 3 steps forwards and one back again, and again. The important thing here is to not try to rush things.
Metacam can make a bun a bit drowsy. Not as drowsy as opioids, but still noticeably drowsy. Idk if it is about relaxation due to pain relief, but that seems likely, since metacam is tbe same type of med as ibuprofen for humans. I have noticed this side-effect in my own buns. It is transitory though, with long term use it subsides. Many buns benefit from getting their daily metacam-dose divided by half and given 12 hours apart. Rabbits metabolize metacam rapidly. I had a bun that needed long term metacam, and it made a big difference when I started to give half of it it every 12 hours instead of the full dose once per day.
My rabbit savvy vet prescribes Pepcid (famotidine) together with Metacam (meloxicam) to prevent damage to the stomach lining. You could suggest this to your vet perhaps. As many of us hooms have experienced, ibuprofen-type meds can cause stomach ache. Pepcid is otc and inexpensive, but needs to be dissolved in water because it only comes in the form of pills.
Rabbits are normally not active during the afternoon, as you say. Its common for buns to not eat or poop much during this time. My bun will come running for a treat in the afternoon, but once the treat has been devoured, she goes back to her customary afternoon hibernation.
Small irregularly shaped poops are typical of stasis recovery. It just means the bun has eaten less than normal. As long as there is poop, this is not a huge worry. It means stuff is passing through and that is prio one.
It’s kind of good that he doesnt eat too much pellets, since pellets require ample water intake. Some buns will eat pellet mush (pellets soaked in water, plain or mixed with sth yummy like mashed banana), or critical care, from a plate or a spoon.
When a bun doesnt eat much dry food, it wont drink much. Buns on a diet comprised of fresh veg and fresh grass may not drink at all.
I do understand that you are very worried. It is very stressful to have a poorly bun, and it does get expensive. You can weigh Tramp every or every other day and keep a weight diary, that wsy you’ll know if he gets enough calories per day.,(allow about 50 grams plus/minus for stomach and bladder contents).
Rabbits as a rule hate being syringe fed. This is a good thing. A feisty bun is a bun that has strength.
