Welcome Nicolas congrats on your 3.5 days.
This is a great forum with lots of knowledgeable caring people on it.
My withdrawals weren’t actually that bad compared to a lot of people that I’ve read about on here. Use the search magnifying glass on the top right. I bet you could find some threads.
I did a lot of angry power walks twice a day for the first month or so followed up with 2 hot showers a day. Really long hot ones. I was so angry I just can’t drink like a normie. And plenty of sparkling water.
And I use the Breethe app for my guided meditations.
I hope to see you around
