Please be very careful titrating up. The reason it starts @ 25mg and goes up slowly is to prevent side-effects like the potentially life-threatening rash SJS.
Either ask for a 25mg dosed tab or ask pharmacist if the tab can be safely cut into quarters.
Lamictal is an amazing drug for many people; however, it's a drug to take very seriously, esp re: titrating up or down, not missing doses, etc.
I would take it if I could. I had to have an emergency appt at the university hospital's dermatology dept. due to serious rash reaction, which was the worst rash I'd ever seen -- more like a serious skin disease than a rash. Very scary stuff.
I hope it works out well for you.
