The extreme tension he was undergoing prior to the release of "Ghajini" took its toll on actor Aamir Khan. A day before the film's Dec 25 release, Aamir went into "prenatal depression", losing his appetite, his sleep and walked around like a zombie.

"The last 24 hours have been (the) most traumatic... I am emotionally totally drained... just before any of my films release I go into a pendulum mode. One sec I feel very optimistic about the film and the next I'm sure no one's going to like it. I lose my smile, my appetite (and) my sleep, " Aamir posted on his blog www.aamirkhan.com/blog Dec 24.

"On the whole, I am listless and walk around like a zombie. VVC (Vidhu Vinod Chopra)...accurately described it as prenatal depression. The film is about to be delivered and will be out of our systems so to speak. Then, it will have a life of its own which we have absolutely no control over, " he wrote.

The actor also said filmmaking was a tough job and he was anxious over his performance in the Hindi remake of the original "Ghajini" directed by A.R. Murugadoss in 2005.

"It's too tough making films. All the two years of planning, preparation, creative discussions, the struggle to shoot the film and the sleepless nights of post-production ultimately culminate in a three-hour experience in the darkness of a cinema hall."

" (And) this time around it is a remake of a Tamil film, so I am especially anxious. 'Ghajini' was a huge success in the south and Surya (Sivakumar) had done an excellent job in the original. I hope that I have been able to do justice to the film, " he posted.

However, the mass promotionals took their toll on Aamir, and he was down with fever before the movie's release.

"...the last couple weeks have been too hectic and as a result of the exhaustion and excitement I'm down with fever, so I am lying in bed as I write this, " the actor wrote.
