File a 2016 calendar year income tax return (Form 1120) and pay any tax due. If you want an automatic 6-month extension of time to file the return, file Form 7004, Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns, and deposit what you estimate you owe.
You can do the math. Fentanyl lozenges-approx. 7 hours. Duragesic takes a few hours to kick in and is supposed to last up to 72 hours (like how Oxycontin is supposed to last 12 hours) but most people find it lasts 36-60 hours. From my experience I've found fentanyl patches to last about 48-54 hours.
Diphenhydramine takes around 30-60 minutes to kick in. This depends on the contents of your stomach and your metabolism, though.
