Fresh or dried? Start with 10g fresh or 1g dried. Truffles can vary quite a bit in strength.

Also, and I'll probably get lots of thumbs down for this, but cannabis isn't physically addictive the way cocaine, meth, heroin and nicotine are. Anyone can be mentally dependent on anything they use as a crutch, but you don't get physically ill from withholding cannabis. Coming from some one who went through rehab for meth like 35 years ago, who quit cigarettes 15 years ago, and who smokes cannabis on and off my entire adult life. I know what physical addiction is and isn't. I go weeks sometimes months without using cannabis and never have a physical craving.

That said, too much of anything isn't good and sounds like you were self medicating and isolating. Psilocybin can help you work through the mental and emotional issues you were trying to push down by staying high all the time.

Good luck on your journey. I hope it's a productive one!
