Have you recently increased your diet challenges. Often at about the time people get off liquid/soft diets and begin to progress toward normal foods, they begin to get some nausea and stomach discomfort. If that's the case, just back off a bit and baby your stomach until things settle down.
Hang in there...7 weeks is still very early in your recovery. Try to be patient...
It will get better!
Words of wisdom by Eckhart Tolle:
"Whatever you fight, you strengthen, and what you resist, persists.”
“Worry pretends to be necessary but serves no useful purpose”
“Accept - then act. Whatever the present moment contains, accept it as if you had chosen it. Always work with it, not against it.”
