Hi Felix,
Welcome to the forums and congratulations on your sober time. If I could only give you one piece of advice it would be to get some type of support system in place to assist you in your recovery. The world is your oyster when it comes to using different recovery methods. Some of the main players are AA, AVRT and SMART recovery which you can find lots of information about on Google. However different people have different methods of getting and staying sober. Some people just use these forums and post regularly. No matter what method you use I think the majority of us would attest that we couldn't do this by ourselves, or by willpower alone.
I wish you the best of luck on your continuing journey.
Natom.
