Well I take Seroquel which causes carbohydrate cravings so I think my weight gain was caused by Seroquel rather than Lamictal. I have not noticed a decrease in cravings since I have been off. I have been doing some research about the immune system. I am walking, taking vitamins, drinking plenty of water, green tea, etc. I also stopped eatting sweets I have not had a lung infection since starting all of this. I am afraid to be very confident because I have not gone a month without antibiotics for over a year.
