For me it hasn’t affected my sleep. But different people get different effects.

As for breast growth, I can’t really say for sure if it has helped, but over the last few months I feel like I’ve had more firmness than the several months before I started it. But it’s been very minimal if anything. It’s one of those things that unfortunately there is no real research to understand if it does or doesn’t make any difference, only a lot of anecdotal evidence. Anyway, it’s not quick.

Ask your doctor first, but you could try stopping for a bit to see if the sleep issues resolve or if it is something else that’s causing the sleep disturbance.

But in general, what little research there is for transwomen seems to show increasing estradiol dosages generally has been more tied to breast growth than progesterone. I had more growth when I raised my peak estradiol levels to just above 300 pg/mL by changing from 3 to 4 patches. A lot of older recommendations say to stay under 200 pg/mL, but newer ones that take into account that we don’t use the old type of estrogen with a higher cancer risk say 200-400 pg/mL. But I’m still quite small with a 34A US bra size, so I added the progesterone to see if that would help. We’ll see in a year or so.
