Grant,
Feeling 'normal' is what this whole thing is all about and you were able to pull it off for a short while.
I hope this shows you that you are improving. Your nerves, sometimes good sometimes bad is probably a sign they are calming down, even if only slightly.
Patience is the name of this game and keeping yourself comfortable is the way to get through this - but I'm not telling you something you don't already know - just reminding you
Keep up the good work, Dale
