Are you allowed to work on morphine?

The answer to this question would depend on the person. The longer you take narcotics the less effect they have on you. It also depends on whether or not you are talking about immediate release or extended release. Morphine tends to have a negative effect on your mood. Most people become very irritable while taking morphine. As the pills start to wear off and your pain starts to set in you tend to become very short tempered and most of the time mean. There really is no set answer to this type of question that would apply to everyone or most people. There is a different answer for every person. I would suggest just taking the pill at home and really paying attention to how you feel, what you can accomplish, and try to put yourself at your place of work with the experiences you have while at home. Try setting down with a project and see what gets accomplished and how you feel. Good Luck!
