Feeling spaced out and tired after increasing venlafaxine dose?

I was taking venlafaxine 37.5 for like3 yrs & very gradually stopped it in 2016 but was taking 1 pill every other mo. I now had to start July 2 and by 12 day I was tired of not sleeping & anxious. So I did up by only up to half a pill. So that I can slowly up to 75. So I take 37.5 in the am & one half of 37.5 in the evening. & yest afternoon & today I feel good. Yest slept well & no anxiety today. May I ask why you increased it. I stayed on 37.5 bc I was doing fine.

Hi, tinsel! This is a "normal" side effect of doubling your dosage and should resolve within just a few days to a week or so. I imagine your doctor increased your dose to put you up into the therapeutic maintenance range.
Hang in there... you'll be better soon!

I went up to 225mg and found myself lazy, not , caring , kind of devoid of empathy so I went back down to 75mg which I stay not doing much for my depression and anxiety but I am accomplishing things and I’m too scared to try on yet another one
