hiya. i feel for you because i have just gone through the same thing with shauny- he was unbearable!. in the end it was non stop, he never had a break for a few months (but he is a boy, so not sure if it would be the same for female buns) he just got worse, in the end i couldnt sleep with my leg/arm or even head some nights out of the duvet because i would wake up to find him, nipping, growling and grinding against me

. and then he started weeing on the bed (only when i was in it mind) but it meant i was changing my bed at least once a day (in the end i put plastic bin liners down and then a sheet on top and slept under that) but it is soul destroying when the bunny who loved you petting them, and used to lie still turns into a nightmare, only after one thing

.
i was terrified about getting him done, but it wasnt fair on me or on him- so i took the plunge (after spending weeks searching for a rabbit vet). that was about 11 days ago, and he is much better. he still gets a little 'excited' sometimes and ive been told that that could take a good few weeks to settle down, but he hasnt wee'd on the bed once

.
think the op is gonna be the thing to sort your baby out.
i hope your bun gets better soon. x
