My dad went to the doctors about a diet, and the doctor prescribed him 37.5mg of phentemine and suggested a low carbohydrate diet. So my dad tried some of the pills and went on the diet, but stopped taking the pills coz they made him feel funny, so I tried some.

I was recently diagnosed with bipolar disorder and have been on the typical cocktail of Lithium, Abilify, and Lamictal, for over a year, during which I started gaining weight, a common side effect. I felt hungry all the time, even after I ate. I gained about 40 lbs before I spoke with my shrink about it.
I orally took a 37.5MG phentermine I got from a friend when I went to see The Dead. I was apprehensive about taking a pharmacutical because I tend to prefer ingesting natural chemicals. I had a beer while waiting for any effects.
Beginning this morning with one foot already in inebriation from the night before's use of ganja and codeine, I called up my g/f and asked her what she was up for, and we decided to talk all day. Well in the first hour of talking I tried to make premade jello absorb vodka... I'd say this was ok...
I'm always curious to try different types of speed. I heard about phentermine from a friend of mine's mom who mentioned that it made her love cleaning the house. A little bell went off in my head: ding ding ding! Cleaning = speed. I ordered a bottle of phentermine from an online pharmacy without a prescription.
This is the dissemination of my use of stimulants, in this segment my focus is describing the drug generically sold as 'Phentermine'. The real Phentermine is always potent when the formulation is normal not XR, and it always has potential for satisfaction in that respect. But it can be a double edged sword .
Well I woke up one morning and got ready for school. Lately things have been going good but I want to make them better. So I dug through the med. trey. Had alot of stuff but Phentermine just stood out. And the do not consume with alchohal caught my attention.
This is an account of the recreational use of Phentermine, which is supposedly similar to Amphetamines. The pills are 30mg. For this experience I am only taking 1 pill to see how my body reacts.

Hi, my name is Circle of Fiends and I'm a daily stimulant user. Ive tried nearly every stimulant RC on the market, as well as some shittier stuff like ephedra, propylhexedrine and caffeine pills. I wasn't expecting much from phentermine after reading the mostly negative trip reports online.
Finals are coming up and i couldnt get adderall (i got some now luckily) so i decided to try out a weight loss pill called Phentermine that my mom doesn't use anymore. as far as i know its easy to get.
As of now this is probably the most euphoric iv ever been, although side note iv never done meth or anything , but i have done oxies which where super underwhelming but anyway i took 4 37.5 mg phentermines equalling 150 mg.
