This tab is based on tabs by other users, I just corrected the Cm to a C#m.
Now it sounds harmonic and like the original song. 
Play this song from the E on the 7th fret.

Intro - E, Em, A, Am, E,

Em (022000@1)  AAm, (x02220@1)ESedative, (022100@1)
   Em (022000@1)        AAm
it's a sedative 
      E (022100@1)    Emit (022000@1)was my hero 
       Aoh (x02220@1)it was.. 

(Chorus)

     C#m (x13321@4)                  A (x02220@1)                    Bit's (x2444x@1)been a long long time since I've step outside

              E (022100@1)  C#mA Bto (x2444x@1)the morning sun. 
 
Repeat E, Em, A, Am from top.

Sedative, 
it's a sedative 
it was my hero 
and I had a hit 
?????? 
?????? 
Sedative, 
oh it was my hero 
and I had a hit on it 


Repear chords in chorus

What's it really like now 
it's been a long long time since I've step outside 
to the morning sun now 
would you take me out 
and I crawl along now 
it's been a long, long time since I've step outside 
to the morning sun. 

This is just E, Cm, listen to the song to get it right.

My faith in you 
My faith in you


What's it really like now 
it's been a long long time since I've step outside 
to the morning sun now 
would you take me out 
and I crawl along now 
it's been a long, long time since I've step outside 
to the morning sun. 

E, Cm

My faith in you 
My faith in you 
My faith in you

Finish on E.
