Not the user you asked, but I took 800-1200mg a day for a while. Then I finally went to the doc to find out I was having a depression. So I unconsciously tried to 
treat my depression, which obviously didn&#x27;t work out. The caffeine enabled me to get out of bed at all though. Without it I was just sleeping&#x2F;staying in bed all day. 
And coming down from a lot of caffeine really makes you feel a lot worse than not taking any at all, just like the comedown of other stimulants.
