Most cases, it is reversable, however, not everyone will be that lucky. Quit, the sooner, the better
for your
lifelong health. Dont end up like me. I'm only 39, but feel like 89 most days.
I have been prescribed opiates, short term, several times, since detox but only for acute issues (ex-dental problem). I only took them as prescribed or less. Chucked them as soon as the pain was tolerable. Since CFS, they no longer give you a high or 'energy rush'. Which is a good thing.
