Using every other day ?

[Str8]

My friend Meg recently started using O every other day (eaten). She is very strict in never using 2 consecutive days, and she always uses the same amount. She uses this schedule because she finds that if she waits longer than that between doses, when she does take it she gets a mild stomach ache (enough to semi-ruin the buzz). She (obviously) also does this because she wants to keep her tolerance down and avoid WDs should she ever need or want to stop for a little while she wants to avoid having to feel like shit for 3 weeks. She is curious if this is at all possible or if her habit may as well be a daily one (in terms of WD risks) ?
