You should certainly quit caffeine. I don’t take my own advice, and I’m not supposed to have caffeine while I’m on sertraline, but it definitely can trigger mania or even just anxiety. It has for me, many times. My last relationship ended abruptly and in an ugly way due to a manic episode. I won’t go too far into it but I basically became an anxious wreck, and wasn’t myself, drank some alcohol and then told the woman I didn’t want to talk anymore, which was the opposite of what I really wanted. I realized months later that the tea I was drinking contained bergamot which is something doctors advise against consuming on my meds. No wonder! Anyways, my shrink wants me to switch to decaf coffee but I very dumbly enjoy the rush and always pay the consequences later. I am a fuck up though so hopefully you have better luck controlling yourself than me.
