To those struggling - you are going thru withdrawal. And you will be ok.
To those of you that are only in the beginning and finding it hard please listen to this podcast with Anna Lembke. It's all interesting but 45:54 specifically. Anna says that the first 4 weeks of abstinence from a drug of choice will be the most difficult (ex spouse was a source of pleasure too). Anxiety, sleep disturbance, sweating, stress. The episode generally described that in such periods we tend to turn to our other sources of dopamine to soothe ourselves (alcohol, drugs, various habits). But after 4 weeks dopamine system starts to reset, pain-pleasure scales balance.
So brothers, stay strong. I know it's very hard, but give it time. Humans have miraculous ability to heal. I hope you find the episode helpful. Stay away from cheap sources of dopamine (drugs, alcohol, phone). Or at least limit. Work towards healthy sources of dopamine - something you need to work for - gym, cold plunges, good diet, proper sleep.
Wishing you sustained recovery and prosperity.
