I've been on anti depressants and anti-anxiety meds for over 20 years. I didn't tell my doc I quit analogs, I just did it. Cold turkey. I went high nic and didn't look back. Now, did I have any more depression because I quit analogs? I actually had more, but it was what was happening around me, totally unrelated to my kicking the stinkies. I took inventory. Then I talked to my doc, telling her what was going on, and as an aside, "By the way, I quit smoking"...........and she was like aghast! 8-o She couldn't believe I had held the line on analogs while all this ridiculous "Murphy's Law" type stuff was going on....yep, she smokes too, but we shall see the next time I go in, he, he!
That's me, and depression is different for everyone as are the meds (which I detest) but talk to your doc, take an honest look at what was going on while you were vaping and get a plan. Also another thing to consider is if you consume alcohol.
That does NOT mix well with anti-depressants.
What I find so nutty is that several of the known anti-depressants are used as "smoking cessation aids".......yeah right, I puffed myself silly on those meds and they didn't help at all with the depression!
It'll sort itself out, you've just hit a stumbling block. Re-group, talk to your doc, and go forward!
