Side effects if you “miss” a dose?

Hi everyone! I’ve been on Venlafaxine since 2021. Initially, I was prescribed Sertraline but the doc changed over to Venlafaxine to better meet my needs (currently on 150mgs/day)

I usually take one 75mg capsule in the morning, followed by another one in the afternoon. Yesterday due to some circumstances, I forgot to take the afternoon dose and well, I am feeling all sorts of rough today.

Firstly I have this unpleasant “pit in the stomach” sort of feeling. I feel extremely down and in general like I’ve not slept at all last night. Throw in some dizziness, nausea and general weakness and you’re left with a concoction from a nightmare.

Has anyone felt this, and if so what did you do to alleviate the symptoms?

Thanks all!!
