Day 4: how long do withdrawals last?

I’m 4 days in from quitting porn and masturbation. I’ve tried in the past but I feel more committed than ever. Today I’m feeling more tempted and also noticing my emotions seem to be less stable and I’m getting annoyed/anxious easily (which is usually a trigger for me). I know that’s probably normal, but I’m looking forward to making it to the point where my emotions are more regulated and I feel stable and not like I’m constantly fighting negative thoughts or temptations. For those of you further along in the process, was there a turning point where you started to notice the benefits more than the struggle?
