Definately keep going, that first week was so hard, even on SS+, so to get this far on SS is an acheivement itself.
I promise it gets easier, and I never thought for 1 second that I'd be enjoying the diet, let alone still on it after 6 weeks.
The will power in the first week is hard to muster, but when the weight falls off and you realise you no longer want to raid the local curry house with a truck (I'd stilllike a curry though...some day) you'll see it was worth it!
Good luck!
