Welcome to the community Willy!! Sorry you had the need to join us!
Good to see that you have O2!!
I'd suggest that you clue your doc in on the sumatriptin (imitrex).......for the vast majority of clusterheads the pills just don't work fast enough.....the imitrex nasal sprays work a bit better, but if you have to resort to the use of trex, the best option by far is injections.
The best thing you can do in my opinion is read up on the anti inflammatory vitamin D3 regimen in our files section......you can start on it immediately once you have acquired all of the co factors but you will need to have some bloodwork done to establish your baseline levels.......we've watched this regimen work in folks life with ch for closing in on 10 years.....works well for about 75 to 80% of folks to either reduce the frequency and intensity of their hits or become painfree!! The originator of the regimen, Batch, is active on the forum so ask any questions you might have and someone will have an answer!
The last option is busting and you'll also find extensive info on that in the clusterbusters files or the share your busting stories section of the forum.
