Hello @goodsouldept -
I am sorry to hear that about your diagnosis! I can imagine that was not an easy diagnosis to hear, but it’s great that clipping is coming up so soon, and I am sure it will be over before you know it.
Like @Moltroub, I am from the “other” side of the family in that I had an unknown aneurysm that ruptured.* My repairs were endovascular, so I have not had any clippings, although I have had a couple of VP shunts, so I did have some experience with more “traditional” brain surgery (shaved head, etc., etc.)
After my experiences, one of my wishes for our healthcare system is that you would get discharge instructions BEFORE your surgery so you have a better idea what to expect and how to prepare while you still can (e.g., you can’t bend for 5 days, have enough food for a week, etc.). Even though I never had a clipping, I wondered if this Oxford University Hospitals (UK) guide on what to expect after cranial surgery may be of interest to you.
It discusses the different types of headaches you can get after cranial surgery, and I also like “Linda’s helpful tips.” (former patient).
During one of my VP shunts, I did throw up after surgery. The anesthesiologist did warn me in advance that it might happen, so it wasn’t really too much of a surprise that I actually did: the doctor knew what he was talking about. 
Going into subsequent procedures, I typically mention it to the anesthesiologist and say, yeah, that happened, and I point to which surgery it was (so they can look up what I was given). It has not happened since, so they seem to avoid using that one again. I am sure you have already taken a look over, but I just found this UCLA flyer with tips on how to deal with PONV. Betting you know them all, but just to be 100% sure!
I am sorry I can’t offer much experience with clipping recovery, but I am sure that those who can will be chiming in soon.
Wishing you all the best!
