I started lamictal a week and a half ago. i've developed muscle weakness, hand tremors, and frequent urination. is this normal? will it go away?

Very concerning: You should notify your doctor of these symptoms at least by phone right away given the upcoming holiday, so that next steps can be agreed upon. The side effects you note are not uncommon but should not be ignored. As with many medications the list of side effects is extensive and some side effects are more serious than others. The urination change and muscle weakness need to be addressed quickly.
