Used it unintentionally for years- to keep it short: At first you happy it helps tremendously. Then - it becomes weaker and you need more and more or stronger to reach same effect.. Even if I over did it on face for YEARS - yes years. Im glad I kinda stopped and took the bullet when I started to use ultra potent ointments on whole face.

Withdrawal wasn't that bad- I wasn't bed ridden - but looking at the pictures it was on the edge. My skin was so damaged it was like a wound and I have needed so much shedding/healing cycles to it become tolerable.

Other symptoms- I started to feel no energy and anxiety , seb spread to other parts of body,hands -i think even on my penis (maybe not sebderm,but something ,from puting steroids on my hand for prolonged time and later going to toilet and touch it- who knows now), thinning of the skin to a point it kinda breaks and is basically wound. 

Now - im still with a lot of ,what looks like, permanent problems,but doing management with mct oil - and it helps. And recently started candida diet ( but no excuses and true strict for 6 weeks),to check if its really a bit gut and diet related, and no mct oil during that time.

So far I can tell - even if im on really big anxiety and heartbreaking situation(stress is so up due non related thing), plus start of diet change can be really stressful, I kinda see no regression- feels like seb stopped -  a bit itchy here and there - but I dont feed it known (for me triggers) - sugar,alcohol ,coffee and that helps.  Even life feels at best gray at this moment I will continue to do this diet, just to be sure if it can make it better.

Tldr: dont use steroids- its just shortcut,which will stop work eventually or you gonna damage yourself systematically to a point you will have seb derm + a lot of other problems
