I take Effexor and cannot sleep. I am 225MG. Right now my anxiety is higher due to the increase and lack of sleep. The doctor said i could take 12.5 MG of seroquel. It does knock me out and make me feel better, however i do sometimes wake up to use the washroom. Has anyone had good experience with this med for anxiety/ and or sleep. I don't want to gain anymore weight that i already have from meds. I'm constantly craving sweets and i need to cut back on that.
