Medication Changes . . . Yuh, Right!

About a month ago, I was beginning to change medications.  Take a new pill and eliminate an old pill, pretty simple.  It would be simple if these drugs were not messing with our brains and did not have lots and lots of side effects.

I was doing ok with the new drug until I was in the middle of the transfer process.  Then I started to feel speedy.  There may have been two reasons for this: either the new drug was causing it, or the old drug was causing it.  I feel like I am in my own mystery story.  I decided to take a step back to where it was comfortable with this new drug.  Then I took a blood test that may show whether the two drugs are interacting in a bad way.  However, the blood test results are not yet available.  If I assume that the blood test is inconclusive, then what do I do?  Go forward and hope for the best?  Or try yet another drug?
