I would echo what others say about starting slowly. I have had my IMCr for six years now and do a bit of IMC flying but I wouldnt use it in anger. There are limitations in services and options that are made available to those with a full IR. Dont rush to fly at minimums (personal, or legal).
As others have said, its all in the planning. Next time you do a route, make it compatible with both a VMC flight and an IMC flight. I.e. plan a route based on VOR's, NDB's, Waypoints you can put into a GPS etc.... That way if your flying along in VMC but want to be go for it and head up into the clouds, then your prepared and ready. If you decide to stay VMC, fine, you still have a good route and can practise some VOR tracking or something. This method also suits me, because my decision to fly in IMC might be based on whether I can get a traffic Service once in the air. Where I am base, Farnborough Radar is an excellent service, with massive coverage in the South East of England, but there are no guarantees to get a radar service.
Additionally I carry Pooleys plates for all airfields en-route. I carry plates for any instrument approaches at airfields that I might use at the end of my route. I also note on a basic PLOG what heights CAS begins at, and also who might be able to give me a radar service should I need it in a hurry. As mentioned before, its all down to planning.
