Gedarim are good, but they need to be complimented with more strategies to have an additional safety net, especially strategies that increase your internal self-control.
I'd suggest doing the following daily exercise, it will take only a few minutes.
Step 1: Imagine a recent tempting situation, then tell yourself "Stop!" or "No!". Or imagine seeing a Stop Sign.
Step 2: State the top 1-2 negative consequence if you give in (e.g. I'll be ashamed and disgusted).
Step 3: Take some deep breaths for 5 seconds to relax.
Step 4: State four or more alternatives that you can do right now instead of P&M.
Step 5: Visualize yourself doing one of those behaviors.
Step 6: Imagine how great you'll feel about the fact that you overcame the temptation.

Another idea for a daily exercise goes like this. The abbreviation for this is SOBER. It takes about 3 minutes.
Imagine a tempting situation, and then...
Step 1 - Stop, Step out of autopilot mode. Tell yourself, "Stop!".
Step 2 - Observe - Shift your awareness to your inner state. What bodily sensations do you notice? There may be some tightness or clenching, tingling or numbness. What thoughts are going through the mind? What emotions are here? Label them if you can, or observe them. Simply notice whatever is here right now; not as you would like it to be, but just as it is.
Step 3 - Breath - Focus on your breathing. Notice where you feel your breath the most. This could be the tip of your nose, or the chest and upper abdomen; whatever this is for you, rest your awareness here and begin to notice the in and out or rise and fall as you breathe. Gather your attention and shift it to the lower abdomen. Observe the expansion and the falling of the abdomen. Notice the regular lifting and falling as each breath comes and goes. Do this for a few breaths.
Step 4 - Expand - Allow your awareness to expand so that it includes a sense of the body as a whole, including your thoughts and feelings. Notice the weight and shape of the body. As you rest here moment by moment, in this spacious awareness.
Step 5 - Respond - Respond to whatever you have discovered through the process, with mindful intention. You are now in charge. If you noticed an urge, make a choice on how to respond to the urge rather than just reacting. Realize that you have a couple of options and ask yourself what action you really want to do.

Regarding your original question, I agree that for someone like you (who does not fall frequently) hanging out on the forum can do more harm than good. But it could still be worthwhile to find a partner or mentor to be in touch with once in a while.
