I have seen my T when I was on alcohol, when I was on xanax, when I was on tramadol, when I was smoked pot but I cant say I was high, he didnt even recognize I wasn't sober because Im acting pretty normal except when I took too much xanax I was really slow. When I did it, i did it to feel okay at session, it doesn't change anything in my behaviour or talking but when I take tramadol I become very talkative and sometimes I say things I didnt want to say but it doesn't change anything in my sessions because I'm honest also when Im sober. It didn't help me to talk about difficult topics but it helped me to feel lil bit better.
If I went to session really high my T would be mad and if I were really high he surely would recognize it and I don;t want to get in trouble.
