The OP lists three symptoms and doesn't say when exactly the increase took place. With coffee you would blame how the caffeine reacts in the brain, but of course you would say cut back on the coffee. If the Zoloft did trigger hypomania or some other set of side effects I think the doc would say cut back the dose and go up slower or not go up at all. You would still blame the drug and how it is reacting in the brain since they seem to coincide. Today is Monday so hopefully the OP can call the doc today. I am not disagreeing with your advice just pointing out the possibility of drug triggered hypomania.
