if you are gambling and you are very excited about it and jump up and rejoicing over your winning, your body adrenaline level will increase also.
I just reduced my stake to the minimal because at that moment thinking straight is very hard so when I reduce the loses start looking small so as to remove that flow or rush of anxiety all over my body.
Limiting my bankroll. This usually is enough since my adrenaline rush cools down really fast due to my thinking while I'm trying to deposit more into my account lmao.
Five to 10 minutes of a cold shower will do the trick for me I feel relaxed and there is no need to come back to gamble.
Stepping away from PC and doing physical activities is usually more than enough to keep losses at a minimum.
I'd keep myself distracted and do something else that'll keep my mind away from gambling because it's not good to immediately go back after losing my bankroll.
