It sounds like things are going very well for you, but that this will take some getting used to –but it shouldn't be too long before your body integrates these positive changes, so they won't feel so strange and disorienting to you. You're on your way.
Actually, none of this sounds bad – just different. You may be reacting to the change of it all, even though the changes are positive. You wouldn't be the first.
I don't think the Alchol/Drug imagery is right for this – you haven't been truly addicted to these drugs and this doesn't sound like withdrawal. What you're experiencing is more subtle.
I'd try the Self-Confidence imagery first – see if that doesn't help. It's designed to help you experience yourself in a positive and integrated way, but it's gentle and cushioned, and shouldn't cause you stress. Others that might be a good fit would be Relaxation & Wellness, General Wellness, or the Affirmations.
If you're up for something a little more physical to channel some of this new energy, Tiffany Chen's Step by Step Tai Chi or Shiva Rea's Radiant Heart Yoga could go a long way in helping you quickly integrate and settle into these wonderful changes.
And you might want to have a gentle heart-to-heart with your anxious side, reminding yourself that just because it feels different, it doesn't mean it's cause for worry. Sometimes that's a good thing!
Congratulations, good luck to you and let me know how it goes.
