Tegretol Post Menopause, Butter Substitute, Fried Foods, Perfect Storm, Anti Depressant

I have been on Tegretol for 2 months and have gained 5 pounds. all around the middle. I bought a treadmill and walk on it 3 miles a day every other day, have only salad for lunch and a 100 calorie muffin for breakfast with olivia butter substitute. I don't eat ice cream, fried foods, chocolate. and I can't drop a single pound. the perfect storm has arrived, post menopause and a need for anti depressant to treat onset of post herpetic neuropathy (after effects of shingles) to be fair, I was on elavil for 9 months and gained 15 pounds. so I am now 20 lbs heavier and despairing that my body is just growing and growing. I have gone up 2 pants sizes already. I eat very healthy and exercise and have not been able to lose one single pound and now I stay off the scale. I got on for the first time in three weeks and guess what? I gained 3 pounds. I hate taking this medication. I feel so fat.
