Does anybody here deal with these? I can't say exactly what it is or what causes it because I don't know. What I do know, I am almost a professional at riding these out now. I've given up looking for help a long time ago. I've given up drinking myself to sleep every night because that started to work only every second night, then third and so on. Certain strains of weed worked best, however it took me a long time to figure out which ones plus that's a whole other can of worms (illegality, supply, cost etc). What the absolute F' is causing this? And how can I resolve it at the deepest level then keep it from not happening in future. I'm not complaining or anything, but it clearly is driving me mad. A lot of people noticed me talking to myself today whereas I didn't because thats becoming my main coping mechanism.
