Hey, the shortness of breath (not being able to take a full breath) sounds like anxiety to me. Some people started dipping to deal with anxiety in the first place (Me). When I quit (110 days ago) I was quickly reminded of this. I had nasty panic attacks that landed me in the hospital. If this continues I recommend seeing your doc. Lexapro is the med I take. It is great because I experience literally no side effects and it is non-narcotic. Just fyi, because I thought all anxiety meds where like xannax and other addictive types.
Craves, to me, are those times in the day when I momentarily lose site of my Quit and consider, even if for just a second, the idea of putting a dip in. You will gain the tools necessary to smack these thoughts to the ground...that is, if you stick to your guns (This Site) and read, read, read.
