"I have been under chronic stress for three years, and I had become increasingly non functional with anxiety and lack of focus, with seemingly no way to “turn off” my stress response. I was easily triggered into extreme overwhelm states. Since taking Phenytoin, the last four days, I immediately felt the effects and I have not been stressed out at all for four days. I have not felt this good in three years. I can focus and I actually feel happy. Granted I only just started it, but have had no side effects."

Dilantin (phenytoin) "My doctor prescribed Dilantin for anxiety and depression. It seems to work just about 60 to 70% of the time for both conditions. Other times I can't really tell the difference. I use 1 or 2 - 100 mg Capsule(s) a day or only as needed. I like that it is not habit forming and tolerance is not built up. Side effects need to be looked at, although I don't experience any serious adverse effects. Extra Vitamin B-12 and Folic Acid needs to be taken while taking Dilantin because it may cause a deficiency with these nutrients."

"I first learned about Dilantin for anxiety and depression in the book, A Remarkable Medicine Has Been Overlooked. It worked for me, and I could feel the results in 45 minutes just as reported in the above mentioned book. It's an old tried and true medication, and I would recommend that you try it if you have anxiety or depression."

"I started with 50 mg per day for two weeks and then 100 mg once in the morning. Amazing drug! No more panic attacks and wonderful for anxiety. Also, I experienced vivid dreams."
