I have heard that side effect with some people.

Honestly, 100 mg is a really low dose so I am surprised it is making you feel tired. Perhaps it's too much for you?? If you are so tired that it could interfere with your driving then I would definitely tell your doctor. What time do you take it? Perhaps if you switch it around and take it a few hours before bedtime, that would help.

I wouldn't, of course, do anything without talking to your doctor.

I was prescribed lamictal as well. My doctor told me to take 25mg for a week, increase to 50 mg a week, 75 mg a week, and then to 100 mg. (maximum dosage -I was told). After the increase to 50 mg, I was so weak and could not function. My doctor told me to decrease the dosage gradually, and discontinued the medication. Did a psychaitrist put you on this - it is a really strong medication from what I understand?

My psychiatrist started me on 25 mg. of Lamictal. I was already on Paxil for the last 12 years. I was soooo slow that I decreased to 1/2 a pill a day. She has now added Seroquel and i have increased back to 50 mg. as of last night and i slept this morning till nearly noon. I'm not sure of my cocktail. Paxil CR 25mg.,Lamictal 50mg and increasing, Seroquel 100mg. last night and now have added Abilify if I cant stand the joint pain of the Seroquel. Any advice?

Report how you are feeling to your doctor. The dose may have been increased too much in too short a period of time. Let your doctor know so he/she can evaluate what is going on.

I have the same problem, I was put on a higher dosage then you but I had the same problem of memory lose plus being unable to sleep. Instead of starting me off so fast, what they should have done according to my new shrink is to graduately moved me up. I was slowly moved up to my current dosage and it seemed to reduced the side effects. I would talk to your doctor about this problem, they likely will need to up you graduately, good luck.
