For a little bit of history, I've been dealing with depression my entire life, and that's what has unfortunately lead me to the situation that I was in. I began smoking weed in middle school, it wasn't until high school that my interest for other drugs began to expand.

Summary
Self-reports cluster around four oral bands: a perceptible threshold cognitive lift at 12.5-25 mg, functional mood balance between 50-150 mg, pronounced but sedating effects at 200-300 mg, and heavy 400 mg+ experiments that many posters later regret. Clinical references corroborate a long half-life (25-33 h) and flag potent pharmacokinetic interactions—valproate can double lamotrigine levels, while carbamazepine or ethinylestradiol can halve them—explaining several adverse-event threads on harm-reduction boards. Titration must start at 25 mg every other day to avoid rash; typical maintenance 100-200 mg divided once or twice daily.

Tolerance
Tolerance Decay
Lamotrigine is not typically associated with classical tolerance to its antiseizure or mood-stabilizing effects. Dose adjustments are based on clinical response and pharmacokinetic interactions rather than tolerance. Abrupt cessation can precipitate seizures; gradual taper is recommended.

Context: In June of 2012, I suffered a head injury at work. A concussion has left me in a somewhat damaged state, as it frequently does, and I have concentration, anger, and mania issues, as well as memory loss, word-recall impairment, motor function impairment, and general malaise.
A handful of years back I was diagnosed with epilepsy after having two fits in a day, one while at work (didn't know it was a seizure at first so I just thought I stood up too fast and continued on with my day) and the other a few hours later while driving.
