Hi Diane,
I have had bouts with sleeping issues. Sometimes I take tylenol PM or some other sleep aid. If you think it may be anxiety triggered I have definitly gone through that. My therapist gave me some solutions. If you are interested in what I have learned let me know..I'll send you a PM.
I'm really happy you are able to takes short walks. I try to walk everyday and it really helps the mind, body and spirit. Congrats on cigaretts...that is great!!! Just wanted you to know I'm here to listen:)
