I've been on pregabalin for over 6 years now for pain control and while it helps no end with keeping me functioning I noticed my weight creep up a few months after starting it. I know my appetite definitely increased - not as a side effect as such just that I was no longer in so much pain that keeping food down wasnt so much of a battle anymore.

One day I hope to be off it. Til then I know I'll just have to work harder to shift the weight.

Hope you don't struggle too much to get to your goal.

Well I am on mood stabilizers for my Bipolar ,but they are the only medications used for the chronic pain of Atypical Neuralgia. Been on them for years. Also on medication for anxiety and other things like a biggie for me is for my thyroid...........causes a lot of weight gain so all in all I would say a lot of my struggles to lose come from these. I keep looking at the fact that the healthy eating and exercise is a good lifestyle to live for me even if I don't see a huge shift in my weight.

I was on pregabalin for a year and a half (until about 4 months ago when I got switched to some different stuff) and I think it definitely increased my appetite and I did gain weight. I used to find eating sugar-free mints curbed my appetite.
When I stopped the pregabalin, I went through a withdrawal phase despite weaning off it slowly and had nausea and a complete lack of appetite for about 2 weeks after my last tablet. I couldn't face the smell of my fruity shampoo let alone proper food! I just ate really bland stuff when I felt up to it, like rice cakes.
Anyway, gradually my appetite did come back and is now back to normal.
Just thought I'd share that because there are always other options your GP might offer you, but they're not for everyone, it's something to bear in mind. I didn't stop it because of the weight gain, but it was more effective than what I now take.
