Hello!
Well , for what I was taught by my master and my own experience , there is a cleansing period after each attunement, be it the first,2,3rd. however everybody feels it in a different manner I had students who had very powerful cleansing experience in one level( i.e physical, mental or emotional) or another and I had students who only needed some time to "digest" and integrate the energy from the attunment. So to answer your question more directly, In my experience there is a cleansing process and even though there sometimes are similarities on what people experience during that period the vast majority of the time it really depends on what needs to happen with each person, so there is no need to "expect" a specific type of reaction.
