For people struggling with insomnia, this was me until last week. I got one of those long v-shaped pregnancy pillows and it has really helped a lot - I still wake up at some point over night, but it's more like 5am than 3am, and I'm able to get back to sleep again faster.
I was surprised the pillow made any difference, because I don't really have any noticeable bump yet, but it really seems to help (or is a placebo). I think being able to curl up around it gives my back more support and stops my (inflated like balloons) boobs from dangling painfully and waking me up. It also keeps me warmer, which is another plus.
Had my covid booster on Wednesday along with the flu jab and felt utterly crap (achy, feverish) for about 24 hours, but fine now. Really glad I was able to get it before Christmas, as I'd had the AZ one before (NHS worker guinea pig, so ended up with AZ even though it's not recommended for my age group), which is apparently totally pants at protecting against Omicron.
