Update-
After having a constant headache + neuralgia for 10 days( medication didn't help much) it dissappeared, as strangely as it came.Thank heavens!! I now think altho the "Tegretol" dulled the neuralgia pain - I think it caused the general headache.
Thanks Colinjn - I do take Ibruprophen quite regularly, I think that's the same as Elevil. It doesn't make me tired.
