Congratulations for taking this step towards recovery! Give yourself a break, because transitioning from addictive abuse to maintenance takes time. Your body has been gong though the wringer for a long time. I had severe balance problems for about a week, probably due to the small fact that I was self-medicating. I abused Rx drugs and the doctors who prescribed them for years, so following directions and taking meds as prescribed was a big deal for me.
Your doctor is your best friend during this time. You might consider making a log of how you feel, severity, and timing of all your symptoms. This can help your doctor help you. Don't do what I did, which was taking things into my own control, tinkering with my dose, etc. Things will improve....rapidly!
