> if you drink coffee be aware that caffeine withdraws are painful.

I've successfully used caffeine pills (e.g. some NoDoz brand products) for coffee replacement to avoid withdrawal symptoms.

Specifically I used caffeine pills to give up coffee. I found it easy to taper down caffeine usage to zero by using a standardised dose size.

Additionally pills are a habit change which helps me stick with a plan. I have tapered down using instant coffee but I found that was a little harder to police myself.
