I am not on these two meds and I wouldn't dare try to give you any info. about them. I just wanted you to know that you are not alone in your fear of weight gain.
I was just dx a little over two weeks ago as BP and I made it very clear to my pdoc that I am TERRIFIED of gaining weight. Back in 2001, I was told, by my family doctor, that I was dealing with depression and I was put on Zoloft. Well, after only four months of taking the Zoloft, I gained 20 lbs!!!
I got off of the Zoloft because of the weight gain and sexual side effects and went on Wellbutrin. I lost about 5 lbs. I eventually took myself off all meds and went on prescription diet pills that I bought off the internet. I lost 40 lbs, but I also got addicted to them...go figure...an undiagnosed BP getting addicted to something!!!
So here I am today...off the diet pills and 15 lbs up again. My pdoc put me on Lamictal, as it is supposed to be weight neutral. I haven't put any weight on from the Lamictal...yet, but I am battling with binge eating and feel like I am just going to pack on more weight!!! I have my next appointment with my doc on Tuesday and hope that he can offer me some support (meds??) for my binge eating.
I would suggest you really make it very clear to your doc how scared you are of gaining weight. From what I have been reading, it appears that many of the meds for BP can make us pack on the pounds. The very sad thing about that, at least for me, is that when I am overweight it THROWS ME INTO A HUGE DEPRESSION!!!! I absolutely HATE MYSELF when I am over 135 lbs and I'm currently 150!!!! Go figure... I know that I need to balance what is most important to me...being mentally stable or being a lower weight, but I can't seem to get myself to ever feel comfortable over 135 lbs...it really stinks!!
I wish you the best of luck with this bothersome issue!!!
