"the way lamictal works faster or slow is due to your metabolism. i could go up doses very fast without having the rash but wow i suffered so much while going through this process. it does get worse before it gets better. once you get to the therapeutic dose then things start to improve. now; some of us have vivid dreams. scary sometimes but you get used to them. also it took me at least 5 months until i got its full benefit. and it may cause you insomnia, need some ambien for that. ambien stopped working after 5 months. and so when i tried melatonin it worked pretty well. melatonin didn&#039;t work in the first months on this drug. only worked after the 5 months and then after few 2 months i didn&#039;t need it anymore. i was sleeping well without it."
