I have taken it, it worked wonders for my anxiety and depression, but yes the weight gain was extreme. Luckily it was a wanted side-effect (at least on the drs part lol), but I gained about 10kg.

I think that if it's making you really uncomfortable go back to the dr and have a chat and decide if the weight gain is worth the benefits and relief to your anxiety. There are ways to minimise the weight gain, which the dr may not have talked to you about, like dramatically increasing exercise and activity (I think the weight gain is caused by Avanza decreasing metabolism, so eating less fat etc isn't really going to help). Go and have a chat to your prescribind dr
