Hi Lostislost,
I don't remember seeing you in the addictions forum before, so welcome.
Congratulations on stopping drug use for your pregnancy, there are some people who can't manage even that.
Have you perhaps considered looking into treatment or support groups, while you're pregnant and not using, to help you develop a plan to stay clean once your pregnancy ends. This could be the perfect opportunity for you to build some sober tools.
And having using thoughts or cravings at 5 months is totally normal. I've found that while the cravings have never really gone away for me, they become less intense and easier to deal with, with time.
