Once ignorance is removed ,is the cessation of suffering automatic? As per my understanding the only effort I have to make for the cessation of suffering is to realize the Truth as it removes the ignorance. Once I have removed the ignorance rest of the things happen automatically.

With cessation of ignorance comes the automatic cessation of fabrications. From the cessation of fabrications comes the automatic cessation of consciousness. From the cessation of consciousness comes the automatic cessation of name-&amp;-form. From the cessation of name-&amp;-form comes the automatic cessation of the six sense media. From the cessation of the six sense media comes the automatic cessation of contact. From the cessation of contact comes the automatic cessation of feeling. From the cessation of feeling comes the automatic cessation of craving. From the cessation of craving comes the automatic cessation of clinging/ sustenance. From the cessation of clinging/sustenance comes the automatic cessation of becoming. From the cessation of becoming comes the automatic cessation of birth. From the cessation of birth, then aging-&amp;-death, sorrow, lamentation, pain, distress, and despair all cease automatically. 

Are there any other choices(other than realizing the Truth) I will have to make for the cessation of suffering?
Because as per my understanding cessations are happening automatically once I have realized the Truth. 

If anyone is conscious then does it mean he has not realized the Truth? Because realizing the Truth would mean automatic cessation of Consciousness.

Have you met anyone who has realized the Truth but has no intellect consciousness ?

Here is the definition of consciousness :


  "And what is consciousness? These six are classes of consciousness:
  eye-consciousness, ear-consciousness, nose-consciousness,
  tongue-consciousness, body-consciousness, intellect-consciousness.
  This is called consciousness.
Ignorance does not cause consciousness. In your studies of Buddhism, please avoid this materialistic error many Buddhists have. As a beginning student, it is important to learn the right way, from the beginning. The suttas (SN 22.82) say consciousness is caused (hetu) by the mind-body (nama-rupa). 

In reality, dependent origination is describing how ignorance pollutes consciousness, similar to how dirt pollutes pure water or how dust covers a mirror. SN 46.55 provides some good analogies. 

This is why there are many suttas that describe how a Buddha has no ignorance but remains conscious, such as SN 22.53, Iti 44 and the end of MN 38. 

When ignorance ceases, what occurs to consciousness is it become pure. In other words, what ceases is 'ignorant-consciousness' or ignorant-sense-contact (called avijjā­samphas­sa­jena). 


  If a monk abandons passion for the property of consciousness, then owing to the abandonment of passion, the support is cut off, and there
  is no landing of consciousness. Consciousness, thus not having landed,
  not increasing, not concocting, is released. Owing to its release, it
  is steady. Owing to its steadiness, it is contented. Owing to its
  contentment, it is not agitated. Not agitated, he (the monk) is
  totally unbound right within. SN 22.53
