I would definitely take one for my first time. One is always enough for me, as well as for my larger, higher toleranced guy friends. So if one is enough for them, one should be enough for you.

But I haven't done X in a long long time (a couple years). Maybe the potency has gone down? I dunno. In any case, it's always a good idea to take just one on your first time. Or at least take one at a time.

The only time you should start to take 2 is if you do X like, every day or something and your tolerance goes up. Or, take that second pill if after a few hours you're still not feeling anything from your first pill. Make sure to wait at least an hour or two. X sometimes takes an hour or so to take effect.

It's always a good idea to carry an extra pill on you just in case the first one isn't enough. But again, don't take both at the same time. It would suck to OD on your first time. Besides, everybody is different. Even my guy friends who usually have the highest tolerances with other drugs have the lowest tolerances when it comes to X.

And remember to drink water. You don't necessarily have to drink more water than you usually do, just drink a few sips of water throughout the night, as you usually would. The reason ppl say to drink water on X is because on X you sometimes forget to drink water.
