1) I never throw potions as well.
2) I avoid reload after bad rolls but I allow myself some exceptions (especially for RP reasons).
3) I avoid making meta decisions when it comes to combats. For instance, if the party has no way of knowing that there is an ambush, then I won't sneak.
4) I don't concern myself too much with meta builds, even for the companions. I may look at them but I prioritize the RP aspect.
5) I try to not compulsively loot everything.
6) I try to be more RP and consistent :
Confession time : I do sometimes make decisions that don't always fully fit my character. Not ones that are drastically against my character. But still, not ideal.
Two reasons for this :
* In games with approval system (like Dragon Ages games), I tend to try to befriend everyone and get max approval.
* I'm a completionist. Trying to do all quests and explore everything.
However, in my most recent playthroughs, I've been trying to break those habits more and more.
I don't know if this counts as self-restriction, It's definitely a challenge for me.
