... prescription to 2mg a day. I don't get the refill for 5 days and completely out of my 1mg. What are the different side effects to 2mg? He has me taking 4 2mg a day. What can I expect? I've looked up the different generic brands, I've always taken sandoz 1mg. I tried some that were from rite aid, dark blue football shape they made me sleepy. I took round blue ones from cvs and they did nothing. I liked the sandoz but I have such a high tolerance that it seems I'm taking pills all day to function. Is the greenstone better? Will it last longer? And now that I can't even feel the 1mg sandoz actually kick in and work, will I fell the greenstone and they work?
