I hope it eases up. My guess would be Lamictal since it's new but that would be a bummer. I had the same problem on Celexa and was diagnosed with TMJ in 2013... It got to the point where I was having vertigo every day due to tight muscles in the neck from clenching. Not fun!

Doc wants me on Lamictal and think I will have to try it now... So I hope it doesn't aggregate my TMJ or cause grinding!
