comedown does not feel to bad at first,but it still boshes your head,and makes you feel down for 3to 4 days!tolerence comes pretty fast as well! first time is always the best! my play days are over for a while ,with drone,and i recomend to people who are are fiending on it ,to take easy! i think it is a bit of a dodgy chemical WHICH IS DEF NOT GOOD FOR YOU!!:wink:
