Yo I’ve been 3 1/2 years sober but I still crave

Like you would think over this amount of time I would have zero cravings but I’ve had 3 dreams the last few nights that I’ve gotten high in or dope has been in. It’s always there, sometimes it’s easier than others. No thoughts at all, life is normal for months then boom a hard day, month, week. Does it ever get easier? Give me a break..
