I think sleeping issues are part and parcel of early recovery. Read up on Post Acute Withdrawals (aka PAWS). Just being aware that it's pretty normal in early recovery was helpful for me. Ive found that trading sugar and sweets at night (for alcohol) was a catch-22... It made the cravings lessen but I felt like crap the next morning. So my advice, be easy on yourself, read up on PAWS and stay away from sweets at night!
