SWIM First time with Ket

[Gas-Head]

SWIM and SWIM's friends are trying ket for the first time next month. They are purchasing 2g (0.5g each) through a reliable source of one of SWIM's friends. SWIM's friends have all done nasal drugs before such as speed, coke and MDMA, SWIM has not but has taken other nasal substances before.

The plan is that they will have a few joints, take some ket, take some Nos while waiting for the effects to kick in. SWIM wanted to know if they took the Ket at 2pm if they would be in a fit state to drink and smoke weed by 7 or 8pm as some more of SWIM's friends will be joining them? SWIM has read up on the forum and discoverd that effects should last around 5 hours which SWIM belives would be fine but just wanted to be sure.

Lastly SWIM was also wondering in what size lines SWIM and SWIM's friends should consume there 0.5g of ket each? SWIM was considering 0.2g then using the rest of pick ups in quantatites of 0.1g but wanted to check with more experienced users.

Thank You in advance
