book by a vanity publisher came out a while back proclaiming the vcirtues of dilantin for
everything from acne to airsickness (joking). The studies regarding dilantin
are, to my knowledge, largely anecdotal, and there have not been good double-blind studies regarding the effectiveness of this drug. The trouble is with your situation is that there is a placebo affect, and whether or not your improvement was due to the use of the drug is open to question.
