Don't go up unless you've plateaued for 3-4 weeks solid. First couple weeks are always weird and then it settles. I'm on 10 now, don't respond amazingly but I'm down 30 in six months which beats not trying. And yeah the doritos thing - nice to not want them 24/7.
I started on 40mg Pantoprazole two times daily earlier in the year for post-meal heartburn. Then came my initial Tirz dose Friday, and that Friday and Saturday were brutal with reflux symptoms. I plan to take Pantoprazole an hour or more before eating and recheck how things go after this Friday.
