Welcome to Sober Recovery! You have found a great place with lots ES&H (Experience, Strength and Hope) from folks who have been where you are now, or are where you are now.
Nope, no medical advice here as everyone is different.
Her hubby and your parents should talk to her doctor if she gives permission, and ask him/her. Dr may put her in medical detox.
Any detox from drugs and/or alcohol can be VERY DANGEROUS and should be monitored by medical personal.

Please keep posting and let us know how YOU are doing as we do care very much and know how hard it is when there is a practicing alkie and addict in one's life.
Love and hugs,
