I'm thinking of double dosing on my codeine cough syrup tonight
Why would you double dose on cough syrup?
I've always wanted to take double dosing of codeine ever since I was a kid
You might feel like you need more medicine to feel well. But doubling your dosage is unsafe.
I don't think so.
You really shouldn't take more medicine than what is described in the instructions. You could end up getting really sick.
