Yes ,knock on wood, I’ve actually had them cut back to 1-2 day. That’s since starting D3&Magnesium and using O2. I can also affirm that O2 doesn’t seem to work as well when tank getting low. The mask I ordered (clusterO2 kit, Thanks DJ) really makes the welding set up manageable, at least for me rt now. Not sure if I’m back to normal after stopping the Imitrex or if the D3 helped that much but I definitely feel better and the attacks are down. Could this be end of cycle also? Hope community is doing well and maintaining.
