<s>[INST] I just started using herbalife products. Just today I have had many instances where it had felt like my heart is skipping a beat. It has been happening all day and has happened as many times as 6 times in a minute. Should I go to the er?  Is this type of thing common? Do you think it is related to the headline herbalife products? [/INST] Hello,Herbal life products can cause various types of problem like headache,dehydration,bloating,hypertension anxiety etc and this could be due to the component of caffeine in it.However these symptoms may be there in you independent of consumption of herbal life.Whatever the reason,you should go to ER snd get yourself examined and it would be better to stop using these products as they don't suit you.Thanks </s>
