Now that I'm used to the armour, I have no issues with taking both at once in the morning. But before I got accustomed to it, I'd have gotten a bit twitchy.

Another thing, you may have unusual side-effect in the beginning. I got itchy and had a hard time sleeping in the PM. But they went away. It took a few weeks.

If you have a hard time tolerating it, start with a small dose and gradually increase by .5 grain every week or two.
