Magazine reports have revealed that Sharon (Letitia Dean) heads to an addicts' support group later this month, giving viewers their first glimpse at her secret struggle.
Sharon finds herself under pressure in upcoming episodes as Phil Mitchell (Steve McFadden) plans a revamp at the Queen Vic, which includes asking his former lover to get back behind the bar.
Unfortunately for Phil, Sharon isn't at all keen on the idea due to the bad memories that the pub holds for her.
When Phil seems reluctant to take no for an answer, Sharon begins to crack under the stress of the situation - struggling to resist the temptation of the addiction she's been hiding since her return to Albert Square.
Keen to stay in control, it's at this point that Sharon visits the support group at the community centre to pour her heart out.
Reports say that Phil later apologises for his harsh behaviour towards Sharon, so it seems that she could be staying at the R&R where she feels more comfortable. But will Sharon be able to beat her addiction, and is there anything in particular which drove her to this situation in the first place?
EastEnders kicks off the storyline on Monday, September 24 at 8pm on BBC One.
