Hello, I am having this psychological/neurological problem since 2011 after I met with a serious accident which caused internal-bleeding and blood clotted in my brain but it got fine with medication and no surgery was required. Then my doctor prescribed me 'Epsolin tablets for around a year. The composition of tablet is Phenytoin Sodium (100 mg). To be frank, It took me 8-9 months to fully recover physically and mentally. Then during that time-period I faced this problem which is explained below: It happens for one full day. On that day, When I wake up in the morning I am totally depressed and my head feels heavy. Thoughts of death come to mind so often. Then a memory blinks in my mind which is always related to some adventurous nightmare I saw previously. When this memory blinks, my heartbeat fastens and feel dizzy for 9-10 seconds and then recover. This keeps happening until I go to sleep at night and wake up next morning. It totally takes me two days to fully recover from this state of mind. Facts: 1. Intensity of the effect which occurs after blink is reduced since starting. 2. Frequency of the problem is also less now. As I mentioned in the description it happens once a month now. 3. Nightmares which blinks in my mind are always those which I saw on the same day previously. It is full of adrenaline rush for example someone chasing me, hanging from an aeroplane etc. 4. I have never explained this to anyone. I tried once but none could understand it. I couldn't even find out that whom should I consult. 5. I have tried sleeping during day to see if it goes away after that nap but it was not working. It still remains until night sleep. Please help me. Tell me something. I am so confused. Thank you in advance.
