Hello....
Thanks for your query. Venlafaxine belongs to SNRI group of antidepressant or anxiolytics. As you rightly mentioned, the side effects of venlafaxine include sleep difficulties and other side effects that you had mentioned which we refer to as anticholinergic side effects. You would develop tolerance to most of these side effects by 2 weeks which means you would no more experience these side effects significantly. However, the drug would require atleast 4 weeks for onset of action as you had rightly mentioned. Wish you good health.
