Due to stomach issues I decided to replace my daily coffees with caffiene tablets. In addition I found that the colour of my teeth improved since then. Also, with heightened sensitivity to caffeine I've moderated my intake.
@JR5 and others - the following may or may not be useful to you depending on your biophysical state and circumstances.
Modifications
Some adjustments I've made at times, which have helped to reduce stomach/oesophagus irritation, sooth the jitters, minimise the elevation of immediate heart rate [and hopefully longer term heart issues] (1-5); heighten focus (5); reduce the incidence of caffiene-withdrawal headaches (6); reduce difficulty in getting to sleep (7); and buffer neurotransmitter desensitisation (8).
- Wait 1-2 hours after waking to have my first dose (during this time I will get sun exposure, do stretching, have a shower and do other things to help speed up the natural waking process, plus:
- Drink 500-800ml of water/fluids before having my first dose.
- Take 2-4 small doses throughout the day, rather than 1 or 2 large doses
- Avoid mixing with other stimulants
- Alternate combining caffeine with L-Theanine OR Glycine OR Ashwaganda/Bacopa in a cycle
- Use the minimum dose needed for my purpose of the day, e.g., important meeting = higher dose, weekend chilling = lower dose; use moderation and conscious use as a guiding principle rather than maximising my pleasure or using it out of habit.
- Conclude all intake within 8-10 hours of bedtime
- Ensure at least 1-2 days per week are caffeine free
