13 lbs in 3 weeks is a major gain, especially if you are not all that big (me, on the other hand, who is somewhere around 400, it's not that big). Your body could just need sometime to adjust to the new weight and the new eating habits. Right now, your body is a bit out of whack and in something that it isn't exactly familiar with, so if you give it time you should be OK.
If you wanted some advice, it's awesome that you have a great gain out of the starting gate like that, but I would take it down a notch. Just general overeating and a dessert or two, because if you go all out, you will experience what you are now. You can always eat more as time goes on.
Also, you get to savor every new pound, which is a perk itself.
I agree,take your time...the human body need stime to adjust to change,be it weight gain or loss or any other kind of major change.Also,how much of what you are eating is sugar (remembering that a lot is 'hidden' in processed foods)?Sugar gives you a quick energy boost,but that is followed by an equally abrupt 'down'.Bananas give energy,but release the sugar slowly and therefore avoid the low.
ENJOY your weight gain as I do mine..enjoy eating and try to not look at it as a race,although,as a gainer,I understand your impatience
