Morning sickness (without the pregnancy)

First important detail, I am 100% not pregnant. Now that’s out the way.. Does anyone else throw up in the mornings? Pretty much every time I get up early (say, before 9am) I end up being violently sick. It’s been happening for quite a while now, a couple of years at least. I used to think it was because I was a lazy bum and getting up early just disagreed with me, but then I started working, and doing things, and generally being productive.. and it still happens. I’ve tried eating, nibbling dry biscuits before getting out of bed, boiled water, boiled water with mint/honey/etc. Does anyone have experience with this? It’s kinda making my life a misery as I have to get up extra early to make time to throw up.
