Topamax is a crazy stuff. I was on it for a summer and I couldn't remember anything! I'm a nurse and let me tell you, my boss actually thougth I was coming to work drunk because of the way I was acting. Needless to say I stopped taking that medication shortly after.
The amitryptlyine was a terriable experiance for me as well. The very first dose of 10mg (yes only 10mg!) I had blurred vision and I couldn't see anything other than colors for the half life of the medication.
I'm so tired of the ER blowing me off as a drug seeker... I wish they knew what it felt like to have daily chronic headaches.
I'm getting botox injections next month. Hope it helps. Good luck to you all.
I can almost guarantee it was the Amitriptyline. At least you stopped at 35 pounds - I gained 70lbs. I stayed on it because the pain without it was SO bad. Only about 25% of people who take it gain the weight but if you are one of them then there you go.
It will take a more than a week to get it all out of your system but how old are you? The younger, the faster the weight will come off. I would blow off the weight loss until after the surgery.
Sorry to ask but do you go a healthy amount of a bowel movement everyday? With this combination of meds I am betting you have alot of stuff in you. Plus you are going to have surgery which will constipate you too. I would ask the surgeon if you can start on a couple stool softeners a night for a while - depending on the answers to above.
By the time you are cleared from surgery, talk to the doc to make sure it is OK to workout and I bet you start losing weight soon. I'm not a doc, just my two cents.
