I started taking Lamotrigine as a mood stabilizer about four months ago. I used to smoke regularly for anxiety before I got on it and have decreased how frequently I do smoke now because of how manageable my anxiety has been. I have been struggling with sleep and my psychiatrist suggested adding on a low dose of Trazodone to help me fall/stay asleep. 

Here's my problem; I have an intense fear of gaining weight. I'm in remission from Anorexia/Bulimia but still struggle greatly with body image. I legitimately panic about gaining even 2-3 pounds. I stopped taking birth control pills even though they only made me gain about 5 pounds despite how much they helped with excruciating cramps/pmdd. I still weigh myself on a daily basis. 
I've only ever been on Prozac as an antidepressant before (5 years ago) and it had increased my appetite, making me gain 10-15 pounds. The Lamictal has helped me so much, I really want to be able to try this new medication too and see how it does for me (can't hurt to increase those serotonin levels) and I would really appreciate some feedback if anyone has any of weight loss/gain side effects. As of right now it isn't too crucial for me to be on this medicine but if it could be helpful I'd be so proud of myself for giving into trying it out. 
Thanks in advance. &lt;3
