I have been taking ventaflne for about six months over that time I have gain about a 25lbs in weight yet my dietary regime has not changed. I have also been suffering very bad headaches and night sweats.
Has anybody experienced the same symptoms
Yes, I think they are common symptoms for taking venlafaxine, most ppl get them unfortunately
Defo the night sweats. Some weight gain but not vast amounts. Seem to sweat all day!
Yes, definately a side affect of the medication.
I'm getting really bad headaches too. Doctor told me to stay away from codeine so I'm on aspirin. Seems to work but the codeine works much faster 30/500g
Yes I put on a lot of weight with this drug. We all get different symptoms with it. I think some people do not gain weight, but from what I have read on various sites, it is common to gain weight. I have also experienced other smaller symptoms.
yeah I gained kilos when I went on as well.. 55kg to 70.
Then over 2 years went back to 60.
Coming off the VF cold, I'm 65-67 kg but I'm enjoying food so I think im eating more 
VF must make some initial disruption to appetite, or metabolism?
I used to sweat so bad. Also gained 40 lbs . Been off 2 weeks now . Losing appetite and sugar cravings! Crazy drug I am hanging tough. It's not easy!!
Sounds like everyone is getting something different...
I've become more Intolerant (for the time being). "WHY did I do that?"
I thought it was because I am mentally trying to 'get up' and fix the stuff that i've been wanting to do... sort of the Army type "RIGHT at 11.00 hours you WILL do xyz!!"
I only noticed a stress induced sweat, so maybe I should humbly count myself very lucky that I don't have that all the time. I'd get badly dehydrated all the time. Since its summer in Aussie now, I get hit by that only sometimes.
Like this last weekend where I had flu, vomiting, bowel issues *and* dehydration!
Yes, expeienced same symptoms.
I had night sweats when I was on VF even in the cold 7 degree winters in Sydney. Maybe because of bed cover position, my neck / shoulder areas of the covers were soaking sometimes, but didn't seem to be regular.
I put any subsequent very bad headaches down to the body reaction to sudden loss of fluids.
I have just started and I am finding I dont feel like eating anything at all.I hope that doesnt mean anything I should be concerned about.
