I have been taking Effexor now for two months. I have just increased to 150 mg a day. This drug is amazing! I started on it for perimenopausal symptoms like insomnia and Mood swings. I feel great now! I hardly ever cry now, and sleep pretty well. (Took about a month for that to get better). My main concern is the weight gain. I have probably gained 10 to 15 pounds just in the last two months. I feel like I don't get full... I eat more than I should, and I have no energy for exercise. Is there anything that I can do or take to offset the weight gain? Will my higher dose help with energy level or just make it worse ? Has anyone else experienced this?
