Hi
Caffeine can give the symptoms that you have described. To much caffeine can increase anxiety as well so I would not increase this I personally decreased caffeine quite a bit I drink real week coffee now.
Everyone is different from build, organ efficiency damage done etc. This is why some lucky people get much less withdrawal than others. I experienced the immediate acute withdrawal. I also went through PAWS which is post acute withdrawal symptoms however I am back at day 15 now and hoping with fingers crossed that I dodge the PAWS.
What ever you experience is proof that alcohol is poison.
I wish you well on your road to sobriety.
