Can i start retaking citalopram after 5 days missed?

I've been taking it for 3 months and stupidly stopped because i thought i was getting better.

Can i now start taking it after 5 days off or will it take ages to start working again?
Will i have to go through the 2 weeks of awful side effects again?
Any help greatly appreciated x

Yes, you can start taking it again and I don't think the side effects will be much and it should start working again pretty fast.
You stayed on it 3 months already, which was a good start.
