The Hole rocker - who previously battled heroin addiction - admits she struggled with using ADHD medication Adderall in 2011 when she was experiencing problems with her daughter Frances, and will always be grateful to the 'Iron Man 3' actress for offering help. Gwyneth intervened after Courtney sent a string of ''crazy'' unintelligible emails to her pals and the 'Malibu' hitmaker says that was what she needed to make her see she needed to stop taking the drug.
She told Britain's Grazia magazine: ''I was a mess. I needed to get off it. Some crazy psychiatrist told me I needed it and I was writing all these crazy long emails and no one could understand what I was on about. I was alienating my friends. ''Gwyneth believed in me, she is a stalwart and I sent her a crazy email and all I got back was, 'Are you OK for cash and lawyers?' I didn't answer for three days and that was when I kicked Adderall.''
Courtney admits it was ''hard'' to give up the drug, but once she had done so, she immediately thanked her pal for her support. She added: ''It took me a week to kick - it wasn't 'Trainspotting'-hard but it was psychological. I had a lot of sex. ''And then I replied to Gwyneth and said, 'I am not going to answer those questions' - cos, you know, I wasn't OK for cash or lawyers - 'but that you asked, I will never forget.' '' Courtney thought it was ''naff'' when the Gwyneth and her husband Chris Martin - who have children Apple and Moses together - announced their break-up by saying they were ''consciously uncoupling'', but admires the way they are conducting their separation.
She said: ''There is no acrimony involved. Unfortunately 'consciously uncoupling' sounds a little naff. I got the Goop email and I, like everyone else, was like, 'Oh man.' ''But even though it doesn't sound semantically that great, like, would 'nice divorce' be better? They really do love each other and they are trying to do a good thing that isn't often done.''
