Lamotrigine
"I never knew I would ever be able to feel normal again, whatever normal is?  Anyway, I too have struggled with anxiety and depression/PTSD for over 20 yrs.  I began taking Lamotrigine a couple of months ago and literally within a couple of days, I noticed that big ball of anxiousness I used to feel in my chest was gone.. I started with .25 mg and now I'm at 200 mg and am feeling way better.. the downside, if you want to call it that, is that I am starting to have feelings again.  I cry at almost everything but it's appropriate feelings that I think I was prevented from feeling because of the psyche meds I took for so long that did nothing but ruin my life and give me terrible side effects.  I am grateful to have found this medication."
