My fish never took xanax before in its life. It tried taking 1/4th of a bar (approx .5mg) but when it cut the bar it cut a bit unevenly so it ended up taking a bit more than .5, (so it was probably .6 or .7). Anyway after an hour and a half there were still no effects (maybe a very mild relaxation but it could have been attributed to anything). Thus it took the rest of the 1mg. So by now the total amount consumed was around 1mg (half a bar). After another half hour very low effects. Very mild relaxation. Then it took a shot of cognac. Now the effects seemed to kick in. It was a pleasant dreamy relaxed buzz. However it was pretty mild and this could have been the alcohol more than the xanax. Is this normal? People have taken around that amount, or even LESS, and seemed to have felt a lot more.
