Personally any type of sativa relaxes me and indica is the kind that could give me some panic about certain things sometimes because it gives me the body high not the mental high. Thats why I prefer sativa over indica! If your having panic attacks on sativa try indica and then try a hybrid ... you need to experiment alittle. If your smokin 2g a day by yourself of course you might get some anxiety so try 1.5 or 1g a day and see how that goes.
