Are these sentences natural? Feb 7

[Musicgold]

Hi,

Are the following sentences natural to a native ear?

1. We need to change the forecast of these projects back to our original estimates.

2. I am the toastmaster for tonight / I am toastmaster tonight.

3. I am doing this just so that I don’t lie there in the bed feeling bad about myself.

Thanks,
MG.

1. Sounds ok, but I would probably use "for" instead of "of".

2. Either sounds fine.

3. Sounds ok, but I would probably say "I am doing this so I don't just lie there in bed feeling bad about myself".
