Megadeth - Insomnia guitar tab

This should be right, I got it from a book.

The beginning goes like this:

Riff A:

e|-----------|

b|-----------|

g|-----------|

d|-0-0-0-0-0-|

a|-7-7-8-5-7-|

E|-----------|

Then when the distortion kicks in, play Riff A 3 times then add this

riff:

e|-------|

b|-------|

g|-5-4-1-|

d|-5-4-1-|

a|-3-2-3-|

E|-------|
