Just to be clear, when I post about starting with a low dose that is only so as to ramp up as quickly at tolerable to a therapeutic dose, and many won't need to do that. For me it was necessary (ER with full dose initially) and it also may help those who would ordinarily be too anxious about taking it. But the goal is a therapeutic dose and I was told 6 clicks of the pen and above was therapeutic. Of course I aimed for full dose.

I have not been able to tolerate 8 clicks until the very end of my treatment but still had 20% gain in spine and 9% in hip.

I would be curious what your doc said about alternate days. I assume that is full dose on alternate days. I would not be able to do that. If I could tolerate a full dose I would do it every day! Sometimes I alternate 6 and 7 clicks during a week when I am feeling side effects.

The half life is one hour or so so it does not build up to a steady state, so maybe doing it alternate days is fine but my doc suggested lower dose, on a daily basis. For me it is not relevant because full dose even once a week would be impossible for me and I would have quit.
