Lamotrigine
"I asked on this site about my taking 300 mg lamictal for 2 weeks after titrating up and not seeing consistent results. A couple of you suggested I split the dosage and take twice a day. Well, good news! After a couple of days, I started feeling consistently better. If anyone is going through what I was, I recommend you talk to your doctor about dividing the dose. Thanks for all your help. I am getting my life back so I want to help others!"
