I'm on Lamictal only. I started at 25mg, 50mg, 100mg, then 150mg. Though it isn't even much, when I was on 150mg, I felt sort of numb.. so I went back down to 100mg. However, even when I started at 25mg I felt like I instantly felt somewhat better. To be clear, the DP is 100% still there.. but the fear and the bottomless pit in my stomach is less often and is not as bad as it used to be.
The psychiatrist diagnosed me as having mania and possibly bipolar 2 disorder. To be clear, I went through a lot of things before I finally found this psychiatrist who actually helped me (and I'm doing therapy too). I've been on it for exactly 6 months now.
I often still think about suicide (because I wonder if this is permanent) and I definitely still have DP episodes and think about DP a lot.
This weekend is actually the 1 year anniversary of the start of my DP (after a drug usage / traumatic experience).
Not sure if this helped anyone, but thought I'd let you know that it was miraculous for me. Now if it could just got away completely.. where's the switch? Kidding.
