Um, I am also going to throw out my concern as have others. I think too that you are well into the throws of hypo/mania. One of the indicators is being unaware/adamant that you are simply normally euphoric.

Lack of sleep is merely on a list of likely symptoms. It is not I believe a requirement. I think it more important to note if the pattern has changed than the total amount you are getting.

It was explained to me by my psychiatrist that medications require an adjustment from time to time. I still got horribly depressed despite being medication compliant. I too right now am in a Spring fever that I realise is possibly hypomanic.

Take heed of the concerns of friends and family. They are a very good gauge of your health status. They mention their concerns because they care. What great people to have in your life.
