Hairbrush,
Phone & Charger,
COMFY clothes! (Tracksuit bottoms and a zip up hoodie were my clothes of choice and it was the best choice as my tummy was swollen and you don’t have much arm movement)
Toothbrush
Post Op Bra (I have Macom ones and love them)
Slip on shoes (You won’t be able to pull anything on your feet)
Lip balm (It’s common for your lips to dry out after anaesthetic)
You’ll spend the majority of the time sleeping due to pain relief and your in a gown from the minute you get there until going home. The food where I had mine done was lovely but if you have a particular drink or snack you like then you could pack them. I found it hard to swallow after my anaesthetic and it felt like my mouth/throat was dry so I was drinking tonnes and eating things like yogurts.
Hope this helps x
