Dear Sri Krishnan,
I agree with Sri Anand. I came across similar problems,even,at some moments it seems like all my emotions are 100 percent stronger,also,headashes,heat,etc. I have read that the heat is a good sign,it is a cleaning process. Many thing related on that i found in Sri Aurobindo writings and it is quite helpfull for me. I also came to understand that it is best not to pay much attention on that,which is,i must admit very hard at times. But,we stumble once,twice,and every next moment,is much better,we tend to learn from it. Whatever happens,just try to keep awareness on that,that is the best remedy for me.
Also,from my own experience,dont force yourself when your mind is not responding. In the end,we are our best guides,and whatever feel it is giving you uneasiness,like headashes,etc,it is a time for rest. Just listen some devotional music,pray,try not to go to other extreme. But,even if you do,do it with awareness,and just be gentle to yourself. It is all play of gunas,so it will pass soon,and when sattwa is predominant You use that time in the best possible way! With sadhana 24 hours a day. Just dont worry,it is all natural,and like i said,it is happening to me too,and it truly look like madness.

At these moments try to remember that it is only mind playing with you,that it is not real,and try to be observer.
With love and prayers,
