Yes, it gets better! The worst should be over within 5 days or so.
What strength patches are you using? If you are getting strong cravings you might want to go up a strength and / or supplement with a shorter acting NRT like gum or inhaler (or an ecig). The most effective way to use NRT is to use enough to kill the cravings while you focus on losing the habit aspects of smoking, then cut down the nicotine gradually.
2 days is brilliant progress - by bedtime that'll be 40 fags you haven't smoked - keep counting these, they soon mount up and give you confidence. If you do cave and have a fag, treat it as just a blip and jump straight back on the wagon.
Prioritise your quit attempt in the early days: avoid situations where there will be alcohol and social occasions where there will be smokers. If you're craving in the evenings, consider just having a bath or shower and an early night.
Good luck, come back for a whinge whenever you need to
