Quitting Weed

I took a hit on 18th, and haven’t smoke since then. It’s day 3 and I’m feeling the withdrawal symptoms starting up. I’ve been a heavy smoker for years and years now, I have a potential job offer in March I’d need to be clean for. Would it be in my best favor to take a hit and wean myself or continue cold turkey and suffer through it? i need to move by the end of this month and needed to pack today, but im nauseous and light headed and can’t to anything but lay down. Any advice or opinions is really appreciated
