OK, once you learn this it’s easy to find!

Look at the top medium blue bar and click on the ‘search’ feature w/a down arrow? Type into the box that is shown “immuran” And it’ll list all threads [continuous conversations] on the topic immuran.
Click on each post? And start reading! Likely may will refer to web sites and other resources as well as what to expect, how it feels and the less nice aspects of this treatment over others. No sense in starting from ‘scatch’ when so many have invented/or been thru versions of this ‘wheel’! Read, then ask questions! I suspect you will know where to address your questions tho. Always helps to get the rite folks!
Hoping and more that it works for YOU! Truly!
