Medication and spending

So I learnt at age 30 I had adhd
It all came to the surface when I lost my job as a result of some addictions I had formed...
Now my psych at the time put me on medication to help with staying awake and focused.. but not specifically for adhd....

4 years later I found out a month and a half ago I should be on ritalin or dexamphetamine
That it is significantly going to help me
But I can't get in to see the psych till next year

I had been managing ok, but still not the greatest...
But since finding out about the hope, ive dropped to a low

I have blown my nlast two pays on gambling... My partner nearly left me last time... And this only just happened yesterday the second time...

I do it knowing the consequences... I'm not even trying to win... I don't know what to do....

Im going to lose everything if it doesn't stop...

1. Is the medication going to help me that much???
2. What can I do between now and next year to stop it ?

If you have an addictive personality you should NOT be on ritalin or adderall or any form of amphetimine.
