Cannabis Making Effexor Withdrawal Worse? Other withdrawal advice?

25M

So im coming off my meds (225mg of effexor) doing surprisingly well, been about 3 months now (cold turkey) all the god awful normal physical symptoms are basically gone, the only things I'm struggling with is sweating, insomnia and this delayed (only started a couple weeks ago) weird uneasy panicky feeling (makes me feel all hot too) that I think is being made worse by the insomnia, but something else I noticed is smoking cannabis intensifies this feeling for some reason instead of the normal sedating/anti-anxiety properties, can anyone explain why this might be happening? also is there anything I can do to help with the insomnia and sweating? especially now that my main way of getting to sleep is causing me to be anxious
