update: my ct scan came back normal. I still have daily headaches and I need 4 percocets a day to keep the pain down. I've tried just taking one and combining it with a big ibuprofen, but it doesn't work for much longer than an hour. It's annoying to call every week and ask the dr. to write me a new rx (they can't just call it in cuz it's a taboo drug); I don't want to seem like a junkie or something. But it's a good medication; I feel like my normal pain-free self, and I"m able to dispense quality vibes and attitude upon my kids, and that's all that matters
