Noooooooo!

If your body is used to caffeine, yes, when you dont have it you will go through withdrawls and be snappy or more anxious, but its temporary. Once that passes having no caffeine definitely can help anxiety. I have gone to no caffeine off and on throughout my life and I think it really is easier to just go cold turkey (expecting a couple days of UGH) as just slowly tapering for me I find convenient excuses to continue.
