I don't have oxygen atm. I dont think they would allow it atm due to me being in student accommodation. I have verapamil and when the doctors is open I should be able to get my nasal spray for sumatriptan which usually does the trick after 5 minutes or so. It's just here in the UK you get 6 doses per £8 prescription so I ration it and decide only to use it during the worst headaches or when it wakes me up and I have work the next day. If this is your first cycle, welcome to the club. I hope you find a medication that suits you well. Hopefully you'll be lucky like me and only have a cluster period every couple of years or so. I count my lucky stars that it's the case with me and my every sympathy goes to anyone suffering daily.
