Must I chop down a tree in ONE run?

Hi,
I have only about 17 Phlegm. I read somewhere else in this forum that it would take me about 5 minutes to chop down a tree with a Stone Axe:
"Some things in this game just take time. Chopping down a tree with a Stone Axe takes ~5 minutes. This is annoying, so I just go read something (possibly bad game design). A Metal Axe reduces this to 2.5 minutes"
Do I have to do this in one run without running out of Phlegm? I think this is impossible for me with 17 Phlegm, even with eating in between. Or could I do it in several steps:
- Chop first 10%
- Regenerate
- Chop next 10%
- and so on...
If not, how much Phlegm would you suggest for chopping trees without help of other players?
