Hi Mirriele,
You're spot on regarding weight gain.
For those of you wondering why the wt gain my neurologist explained to me it's quite common after DBS due to a sudden absence of dyskinesia and for those with tremor a sudden lack of tremor.
Both are great calorie burners!
I've just started losing weight with regular trips to the gym and a curbing of my chocaholic intake but I wish I'd thought of that earlier!
Cheers,
Lee
