hi and welcome missmycology to SR
Glad you made it here there's a lot of information in posts and a lot of support.
l agree, you should see a GP for a check up to make sure everything is ok,
it can be very dangerous detoxing without supervision and you may even need medication.
Having said that... good on you for taking charge of your life.
A recovery plan can help, AA offers face to face support.
The first step towards change is acceptance.
Once you accept yourself you open the door to change.
Change is not something you do, it's something you allow.
