I just started on Lamictal as well (3 days ago) at 25mg, and I'm pretty much in the same position as you. I've definitely noticed a HUGE difference in my energy levels and I'm so groggy and drowsy. Ugh it's pretty crappy. I was told to take the dosage in the morning, but I am thinking of moving it to bedtime.

Other than the sleepiness, I haven't had any other side effects, and like others have said, it seems like once your body adjusts to the medication, they will go away.

Take care!
