Using the nutmeg with the money drawing oil is a good idea.
Sometimes I've noticed a certain oil works better for me at times and at times other oils work best.
With gambling change is the nature of the beast. Casinos change up slot machine patterns all the time.
To combat this, I use a number of different options.
I have used money drawing but if I find it stops working as well, I'll rotate my oils and use another.
Recently, I've had great luck with Lady Luck products.http://www.luckymojo.com/ladyluck.html
Other good products if your luck seems to change, are the Black CAt products.http://www.luckymojo.com/blackcat.html
Black Cat is popular with gamblers and is used to reverse bad luck.
I put the Lady Luck oil on my fingertips when playing slots.
Best of luck to you!
