I never gave up, but reduced to one morning espresso - no more caffeine during the day. (I mean no tee, coke etc.) With this one espresso I still easily (without any stall) lost 35 lbs in 7 months.
I had very strong headache for one week when I decreased my coffee intake from 4 espressos/day to one, but maybe because I kept the one shot, the headache disappeared very fast.
Having very low blood pressure, without this coffee I have sudden black outs...
From the posts on different threads here, it seems to me that half the members still drinking coffee.
