劇薬中毒

Sure, here are the translated lyrics:

Surely, you are a bitter and sweet medicine
Melt into every corner of my body and ease me
I am now poisoned
Only you can cure me
Toxic addiction

Still feeling the chill in the sky, alone
Hurrying, turning the corner
In the town where you live, the familiar slope
Killing time, stopping by the convenience store

I must not wish for anything
Even if my feelings try to stay
The lipstick you praised
Kept decreasing, that was the answer

I gave you all my lifetime's worth of "love" (all the "love")
I gave it all to you
I'll probably cry alone again today
Even if I'm hurt this much, I want you

Surely, you are a bitter and sweet medicine
Melt into every corner of my body and ease me
I love you more than yesterday
Be careful of the strong side effects

Surely, you are a bitter and sweet medicine
I was drawn to you knowing it's not eternal
I am now poisoned
Only you can cure me
Toxic addiction

Am I drunk or not?
I don't know, that sweet liquor
Without it, you won't
Meet me anymore, right?

Your long hair (long hair) for you
I've come to love it
The world changes for oneself
I feel like only I was left behind

So please cool down this fever
With the medicine limited to once a day
Hug me tighter than yesterday
I don't need to be myself in this love

So please cool down this fever
The alarm has been ringing for a long time
Don't let the fire of our love die
Keep stoking the flames towards eternity

I surely can't come to dislike you (I know)
Because what you gave me is too big
Even if you disappear from in front of my eyes
The fragments inside me will ache and hurt
Kiss me

It tasted like a bitter and sweet liar
I swallowed it whole so I wouldn't notice
I know it's a bad romance
Then hurt me deeper, I love you

Surely, you are a bitter and sweet medicine
Melt into every corner of my body and ease me
I love you more than yesterday
Be careful of the strong side effects

The happiness I lost with you
I hope it doesn't live somewhere else
Today too, I'm wishing alone
Only you can cure me
Toxic addiction

Kitto anata wa nigakute amai kusuri
Karada no sumi made tokete raku ni shite yo
