Hi Jerry, I am taking the new dilantin. I have done my research, and (unfortunately) know about all the problems some people are having with it. I take 300mg. per day, and since I had about a 2-month supply of the old dilantin, I "phased-in" the new pills. I took 2 old, and 1 new for about a month, then 2 new and 1 old, and am now on 3 new dilantin 100mg. every day. I have been on this for about 2 weeks, and I have not had any problem at all.
