I have started with 1 click. I assume the benefit here is that my body getting used to the drug, not that there's massive bone-building going on. FWIW-- I am 110 lbs and 5 ft 1 in, too, and I haven't felt any side effects (yet) at this dosage level. My current plan is to go up a click a week. We'll see how far I get.

You can start with one or two. It doesn't matter. The goal is to let your body adjust to the change in parathyroid hormonal action. You can start at whatever level you can tolerate. If you start with one it will just be an extra week.

If you do have side effects, I hope you can stick with the medication. There are certain side effects that do get better but I did have fatigue, even at 6 clicks. I did better getting up and out though, versus resting!
