I was very responsive to the
lamotrigine, so I lived with just 100mg
for quite some time, and it worked well
for a couple of months. After a rather bad period they finally tested my lamotrigine levels and found out that I was at the low end of the therapeutic spectrum. And that's when it got raised to 150mg. Not everyone is the same, regarding meds.
But yeah, I'm going to 200mg soon.
