You sound like an extremely lucky person to not go through the withdrawal. It is only 48 hours, so there is a chance it could get worse, but by day 5 you will be in the clear. Make sure you are getting plenty of rest, drinking gatorade, eating healthy meals and you will be well on your way.
I myself got off lucky this time too! I'm about to start day 7 and I cant believe how good I feel!! DO NOT TAKE IT FOR GRANTED!!! Cut off all sources from docs or dealers!!! Tell certain people who will hold you accountable and help you though this! Eat healthy if you can and exercise as soon as you can! Look into aftercare! You can do this!!! You may not be so lucky next time! I'm proud of you! Keep up the good fight and everyday gets better! Keep us posted!!!
I have no idea! I would recommend that you simply count your blessings, take a deep breath and thank God!
