longer lasting triptans

So imitrex seems not to last long enough to stop my migraines anymore. The problem is though I already had to switch to the nasal spray because the migraines are coming on faster and stronger lately and my stomach takes forever to digest/adsorb anything during a migraine.

I remember trying maxalt melts a long time ago and got extremely sick from it - vomiting, severe vertigo, shaking etc. I also cant even smell the fake raspberry anymore without wanting to puke so its not an option.

Is there any other triptans with a longer half-life that are not pills? I'm too tired and sore to look them all up like I would normally. I'm getting good success on the first day but it comes back 16-18 hours later and I don't have enough days of meds to treat the second day - 24/7 headaches with 1-2 severe migraines a week that last 2-4 days normally with treatment and rest - no treatment = ER or admitted. I'm already had 8 days of meds this month so this scares me for the next couple of weeks.

Yes I'm on 2 different preventatives (Inderal and Cymbalta -tried topomax and evail with no success), another addition for depression, magnesium (tried the other supplements no success), botox, trigger point injections, and all the natural treatments - chiro, massage, craniosacral, acupuncture, psychologist, prolotherapy. So I am doing everything else I can. fun times, thanks.
