After 5 months of depression (and by my own choice not being on any psych meds except Trazadone) I did research and asked my P-doc for Lamictal. It's taken 4 weeks to build up to 100 mgs. and I admit I grew impatient waiting for it to work. Well, hallelujah it finally happened! I can't believe the difference. So if I feel great at 100 mgs. I guess I should stay at 100 mgs.? Is there any point or justification for increasing the dosage? Thanks in advance for your feedback.
