Lamictal and gaining weight

I've been on lamictal -50mg- for 3 months now. I keep gaining weight no matter what i do. I exercise regularly, i eat healthy and rarely, and i GAIN weight. I have always been able to eat whatever i want and not gain a pound. My whole life my weight has been 115-125 pounds, i weigh in at 165 today!!!!!!!!!!!!!!!!!!!!!! I am so angry and frustrated! My feet and ankles are swollen. I have extreme pain in my knees and i can barely walk when i get out of bed in the morning. My shoulders ache all the time also. I had no idea why this was happening until i read all these comments. thanx everyone! i am DONE taking this med for good!!!!!!!!!!!!!!!!!!

I have been on Lamictal for almost a year now and everything seemed to go okay until almost three weeks ago when I had to increase my dosage from 100 to 150mg and my Lexapro to 15mg. In the last couple of weeks, I have gained 7 pounds and I am really depressed. I have an eating disorder (bulimia) and because of this, I profusely purge my food in fear of gaining a dramatic amount of weight again. I am going to see my psychiatrist next week because all of this is going to cause me to crash.

I am on my 5th day of taking 25mg of lamictal and I have developed a sore blister cluster on the right side of my lower lip, a slight sore on the side of my tongue, my eye lid rims seem to itch, and I have to scratch a random itch on my body. I was just diagnosed as having bi-polar 11 disorder and had already have been taking prozac for a number of years for anxiety. The prozac was not helping by itself anymore and I am finding it harder and harder to keep a job. I, not to long ago, held Director positions in the Human Service field, and am now settling to take a job at a local retail store for a little more than minimum wage. Anyway, I was hoping to get the help I need from this new med but, feel it is probably not the right one for me. What will I be given next? I was given lamictal because of my fear of gaining weight an either depakote or lithium. I will call the clinic tomorrow and hope I will be squessed in to see a Dr. who can tell if this blister is from this or because i ate alot of fresh tomatoes recently. In the past , my love for tomatoes was worth the sore. but, sometomes i stayed away because i did not feel like dealing with the discomfort. Now I am rambling, but worried about this being a potential harmful side affect. Also, I do not need to become any more scattered brain then I have been lately. My own sanity seemed to deteriorate since my daughters behavior since 6th grade became umbearable. She is now in 10th grade and as of 8 months ago is not living with me. She called the police and I was jailed for a night and a day.My bility to cope with life became more and more difficult. I hope to find a regimen that will keep me from applying for disability. I am now 53 years old and have worked all of my life up until now. I feel like a kid trying to find out what I want to be when I grow up. Rambling again but this certainly has been helpful in that It gives me a chance to sort out my concerns. ThankYou
