Oh no! - that's not a good side effect.
How about the weight, has it helped at all?
I have lost 12lbs so far, the first week I was still having cravings but this died down and now I have even gone so far as forgetting to eat! Unheard of for me.
The grumpiness seems to have worn off a lot now I have adjusted but for the first couple of weeks I was snappy and teary, depression can be a side effect and I was actually going to come off them but (touch wood), it seems a lot better now. Still a little grumpy at times but nothing new there! I have been waking up at night sometimes as well so that doesnt help.
