Oh, I am on 37mg effexor and it has made me shoot up! I was told with effexor it is not dose related, ie, with some people the wieght gain is all at the lower doses and not at the higher ones. The lithium is also a problem but it IS more dosage trelated. GRRRRR. I hate this too. Unfortunately I can't help you out much with lactimal... Huggs anyway.
