Weight gain from going OFF Zoloft?

So, I've heard all about weight gain from taking Zoloft, but I'm having an unexplained weight gain now from going off; is this normal?  I'm a 16 year old male (soon to be 17) and have been on Zoloft since about this time last year.  I started at 25mg, and had a gradual increase in dosage until eventually I went from 100mg to 150mg, and then from 150 to 200.  It was in the weeks in which this dosage change occurred that my weight inexplicably shot up from 133 pounds to 158.  I think the highest it ever got was 161, but on average it was between 155 and 158.  Then in February it was suggested that I switch meds, so my dose started decreasing, first from 200 to 150, then from 150 to 100.  In the first week of going down from 200 to 150 I lost 10 pounds.  The next week I lost 4, and that's been about my average weight since February (144).  But now, just recently (the beginning of April) I've gone down from 100mg to 50mg and my weight is drastically increasing again.  On April 6th (the day I switched to 50mg) I weighed 144, and now, 2 weeks later, I weigh 153.  I haven't been eating differently, in fact, if anything I've been eating less and healthier foods, and I've been jogging once a day for about an hour, so I really can't understand why my weight is going up so much in such a short period of time, unless going off Zoloft causes weight gain.  It should also be noted that Zoloft is my only medication and I'm not doing anything else that could possibly affect my weight.  So, is this kind of weight gain from going off of Zoloft normal?  Thanks in advance for any insight on the matter,

Hello,
I am Kitt.
Zoloft could cause weight loss in children. I have heard you may loose a few pounds of weight in adults when you first start it but weight gain is a side effect from using the med.
I, too, have never heard of weight gain when going off of the med.
I suggest you talk with your physician as that is a rather impressive weight gain condsidering your eating healthy and excercising.
Please keep posting.

Diabetes runs in my family. My pdoc once told me that there may be a link between antidepressants and diabetes so I did a lot, and I mean A LOT, of research before I went back on meds. From what I could find out there may be a link between antidepressants and low blood sugar. If indeed the Zoloft lowered your blood sugar than going off of it would "normalize" your blood sugar and perhaps this might explain the weight gain.

So the general consesus here seems to be that weight LOSS from going off of Zoloft is normal, but weight GAIN from going off of it is not?  I'll have to check with my doctor the next time I see her to see if she has any ideas.  I just got my blood drawn a few days ago so that might bring back some results.
