HI welcome to the forum....the pink cloud effect is what some people get when they first come off the pills....suddenly they feel like a million bucks everything is great the world has became a perfect place bacicly over night...the reality is your still an addict and still think like an addict when the ''pink cloud'' wheres off you suddenly find your self overwhelmed with emotions and your new found sobriety is now hard to deal with without a pill...and yes relapse often occurres ...the trick to getting past all this and to long term sobriety is aftercare...addiction just dosent go away after you quit taking the pills its a desiese that requires treatment....both A/A and N/A offer free programs that work if thats not a good fit for you try a substance abuse conslor or a addiction therapist but it is critical to get plugged into something it will greatly reduce your chance of relapse so plug in somewhere good luck and God bless.....Gnarly
This is good article. It basically says that it is when you start feeling better and think you've got it all. This is where relapse starts. Congratulations on your clean time! Stay strong!
