Lamictal I used to take Lamictal 150mg at night, no problems, but started feeling anxious in the afternoon/evening. My Dr. Rx'd 300mg lithium at night to see if it would help the anxiety, but I had very fitfil, unrestful sleep to the point where I was not sleeping much and very tired all day. So, the Dr. took me off lithium and substituted Tripletal 300mg in the evening. That worked, but I was still a little depressed & she increased my Lamictal to 200 mg at night. I started waking up after about 4 hours with horrible nightmares. I thought the nightmares were from Trileptal because that was a new med, but even after I discontinued it, I still get the nightmares/panic feeling that wakes me at night. I took 2mg Lunesta for a while to help me sleep, but then I slept too much 10-12 hrs. I take the Lamictal now in the morning & don't get those nightmares & I sleep fine now, but I feel anxious & dizzy and have trouble concentrating, again about 2-4 hours after I take it in the morning. Dr. says I can take ativan to help the anxiety, but I feel like I need to get off Lamictal and try something else. Maybe lithium will help if try to take it now witout the Lamictal.
