I took Tegretol once, for a very short period of time because it caused a skin rash that would not go away with antihistamines. I only took 100 mg. It created a magnificent effect of no thoughts in me - complete and wonderful stillness. I cannot meditate, but believe it is the effect meditators are after. This was against the backdrop of a hypomanic episode with racing thoughts.

I am wondering out loud if your Tegretol dose is too much for you personally and whether titrating down a bit would resolve these issues. If it is such a potent drug that a tiny dose could bring down racing thoughts to a meditative stillness, a bigger dose can produce brain fog.

Of course we are all different, but still, I am always for trying to work with the dosages before giving up on a med.
