Hey there @Sister , you'll be fine. Take along some nice tea or coffee of your own and anything else you might fancy. I went for salt and vinegar chips which I had to just suck, as crunching them up caused bleeding gums, but the sharp taste was what I liked. The hair thing is a bit strange, isn't it? I was totally bald north and south...felt like I was ten again!!! My arm and leg hair went next and eyelashes, one by one and lastly the eyebrows. For me, the biggest pain without eyelashes, was cat hair getting into my eyes. You don't realise how much dust and fluff and other such stuff your lashes keep out, till you have none. All the hair is now mostly back, but my underarms still have nothing, and very sparse on my legs. When the hair started to regrow, at first I looked like a startled yeti, very fluffy peach down covered my arms, like lanugo on a prem baby.
