all of a sudden caffeine has started affecting me a lot. last night i had a cup of coffee and was jittery and nervous all night. in the last couple months ive been getting more serious about weight training and have been eating more healthfully, but that's really the only thing i can think of that has changed. any thoughts? i love coffee and would hate to not be able to drink it!

I gave up on caffine for a bit and I felt alot better after a few weeks.

Go decaf... its coffee without the caffine... the only difference is in your mind
